Q13 of 80 Page 45

Solve the following equation:

8 (x – 3) – (6 – 2x) = 2 (x + 2) – 5 (5 – x)

Given equation: 8 (x – 3) – (6 – 2x) = 2 (x + 2) – 5 (5 – x)

8x – 24 – 6 + 2x = 2x + 4 – 25 + 5x (Removing


brackets)


8x + 2x – 24 – 6 = 2x + 5x + 4 – 25


10x – 30 = 7x – 21


10x – 7x = -21 + 30 (Transposing 7x to LHS and 30 to


RHS)


3x = 9


x = (Transposing 3 to RHS)


x = 3


The solution of 8 (x – 3) – (6 – 2x) = 2 (x + 2) – 5 (5 – x)


is x = 3.
