RS Aggarwal Class 6 Math Ninth Chapter Linear Equation In One Variable Exercise 9B Solution
EXERCISE 9B
Solve each of the following equations and verify the answer in each case:
Contents
(1) x + 5 = 12
Solution: x + 5 = 12
Or, x = 12 – 5
Or, x = 7
(2) x + 3 = – 2
Or, x = -2 – 3
Or, x = – 5
(3) x – 7 = 6
Or, x = 6 + 7
Or, x = 13
(4) x – 2 = – 5
Or, x = – 5 + 2
Or, x = – 3
(15) 3(x+2)-2(x-1)=7
or,3x+6-2x+2=7
or,3x-2x+8=7
or,x=7-8
or,x=-1
Sir check the ex 9b 26 . how did 3X-3 Came
As it is multiply
3 × (x – 1)
= 3x – 3
That’s it came…
Sir check 9b 24.how =10 came
By Cross Multiply 10 is came Kranti
