ML Aggarwal CBSE Solutions Class 7 Math 6th Chapter Linear Equations Exercise 6.1

(1) Solve each of the following equations:

(i) x + 6 = 8

(ii) 2 – x = 5

(iii) 4x = -6

(iv) x/2 = 5

(v) 2y – 3 = 2

(vi) 4 – 5y = 2

(2) Solve the following equations:

(i) 5(x + 1) = 25

(ii) 2(3x – 1) = 10

(iii) 3x-1/4 = 11

(3) Solve the following equations:

(i) 5x – 6 = 12 – x

(ii) n/3 + 1 = 4 – n

(iii) 5p + 7 = 19 – 2p

(iv) 2x + 5/2 = 2/3 – x

(v) x/2 – 5 = x/3 – 4

(vi) 18 – 3y/4 = 11 + y

(4) Solve the following equations and verify your answers:

(i) 3(x + 7) = 18

(ii) 2(x – 1) = x + 2

(iii) 3x – 1/3 = 2(x – 1/2) + 5

(iv) 4(2x – 1) – 2(x – 5) = 5(x+1) + 3

(5) Find the value of p if the x⁴ – 3x³ – px – 5 is equal to 23 when x = -2
