Simple Equations

 

Question 1:

Write the following statement in the form of equation one eight of x is 5 more than 3.

(a) x/8 + 5 = 3

(b) x/8 – 3 = 5

(c) 3/x – 8 = 5

(d) x/8 – 5 = 3

Ans:

One eight of X is x/8

It is greater than 7 by 3.

This means the difference (x/8 – 3) is 5 the equation is x/8 – 3 = 8/5 (b)

 

Question 2:

Add 9 to three times P to get 100.

(a) 3P + 9 = 100

(b) 3P – 100 = 9

(c) 3P + 100 = 9

(d) 3P – 9 = 100

Ans:

(a) 3P + 9 = 100,

three times of P = 3P add 9 = 3P + 9 gives 100, 3P + 9 = 100

 

Question 3:

Shweta’s mother’s age is 7 years more than four times of shweta’s age. Shweta’s mother’s age is 55 years old. Set up an equation to find shweta’s age.

(a) 4m +7 = 55

(b) 4m – 7 = 55

(c) 4m + 55 = 7

(d) 4m – 55 = 7

Ans:

We don’t know Shweta’s age let us take to be m years. Four times of Shweta’s age 4m years. Shweta’s mother’s age 7 year more than 4m that Shweta’s mother’s age is (4m + 7) years old. Shweta’s mother’s age is 55 years old.

(a) 4m + 7 = 55 it will give Shweta’s age when solved.

 

Question 4:

The sum of three times x and 13 is 34.

(a) 3x – 13 = 34

(b) 3x + 13

(c) 3x – 34 = 3

(d) 3x + 13 = 34

Ans:

(d) 3x + 13 = 34, three times x = 3x it gives 34 = sum of 13 = 3x + 13

= 3x + 13 = 34

 

Question 5:

Choose the correct value of variable which satisfy following equation.

4n + 17 = 25

(a) 1

(b) 2

(c) 3

(d) 4

Ans:

Put n = 1, 4×1+17 = 25 does no satisfy

Put n = 2, 4×2+17 = 25 satisfy the equation solve it so on (b) 2.

 

Question 6:

Write the following equation in statement forms.

7x + 8 = 53

(a) Seven times of x plus 8 gives 53

(b) 8 times of y plus + 7 gives = 53

(c) Seven times of x plus 9 gives 63

(d) 8 times of x minus 7 gives 53

Ans:

(a) Seven times of x plus 8 gives 53.

 

Question 7:

Solve 3P – 6 = 18 and find the value of P?

(a) 4

(b) 2

(c) 8

(d) 3

Ans:

(c) 8,

3P – 6 = 18 add 6 on both

L.H.S 3P – 6 + 6 = 18 + 6

3P = 24 divide by 3 on both L.H.S and R.H.S 3P/3 = 24/3 give P = 8 (c)

 

Question 8:

Solve m/5 + 20 = 45 find the value of m?

(a) m = 45

(b) m = 20

(c) m = 120

(d) m = 125

Ans:

(d) 125,

m + 20 = 45.

Subtracted -20 on both L.H.S and R.H.S m/5 +20 – 20 = 45 – 20 m/5 = 25 multiply by 5 on both L.H.S and R.H.S m/5 × 5 = 25 × 5

= m = 125

 

Question 9:

Solve the following equation 2(x + 5) = 14

(a) 3

(b) 4

(c) 2

(d) 1

Ans:

(c) x = 2

2(x + 5) = 1 divide both L.H.S and R.H.S by 2. 2(x + 5)/2 = 14/2

(x + 5) = 7 subtracted 5,

From both L.H.S and R.H.S x+5-5 = 7-5, L.H.S = 2 = x.

 

Question 10:

3y + 3/2 = 27/2 solve this equation.

(a) 5

(b) 8

(c) 3

(d) 4

Ans:

(b) 8.

3y + 3/2 = 27/2 subtracted – 3/2

From both L.H.S and R.H.S 3y + 3/2 – 3/2 = 27/2 – 3/2, 3y = 24 divide by 3

On both L.H.S and R.H.S 3y/3 = 24/3, y = 8

 

Question 11:

4+5 (P-7) = 84 Solve this equation.

(a) 26

(b) 25

(c) 23

(d) 24

Ans:

(c) 23.

4+5 (P-7) = 84

4+5 (P-7) = 84 – 4

we transfer 4

5(P-7) = 80

5(P – 7)/5 = 80/5 divide both sides by 5

P – 7 = 16, P = 16+7, P = 23

 

Question 12:

Solve the equation x/7 + 20 = 34

(a) 98

(b) 72

(c) 84

(d) 70

Ans:

(a) 98

x/7 + 20 = 34 transfer 20 on R.H.S

x/7 = 34 – 20, x =14 multiply by 7 on both sides x/7 × 7 = 17×7

= x = 98

 

Question 13:

Solve the following equation. 

Add 6 to four times a number you get 62.

(a) 15

(b) 14

(c) 16

(d) 17

Ans:

(b) 14

Four times no = 4 × X

= we take a number is x,

add 6.

4x + 6 = 62,

4x = 62 – 6

4x = 56,

4 × x/4 = 56/4,

x = 14

 

Question 14:

Akshara thinks of a number. If she takes 0 way 9 from 7/2 of the number the result 54.

(a) 14

(b) 18

(c) 19

(d) 15

Ans:

(b) 18.

We take the number is x.

from the above example

7/2 x – 9 = 54

7/2 x = 54 + 9,

7x/2 × 2/7 = 63 × 2/7,

7/2 x = 63

x = 18 by calculating it.

 

Question 15:

In an isosceles triangle, the base angle are equal. The vertex angle is 80°. What are the base angles of the triangle?

(a)70°

(b) 60° 

(c) 50°

(d) 80°

Ans:

(c) 50°

The base angle is x two same angle means 2x.

The sum of three angles of a triangle is 180°. Vertex angle is 80°

2x + 80° = 180°

2x = 180° – 80°

2x = 100°

2x/2 = 100°/2

x = 50°

The base angle is 50°
