prove that

Question:

 [(5(1 – x)) + (3(1 + x))/ (1 – 2x)] = 8

Solution:

We have,

[(5(1 – x)) + (3(1 + x))/ (1 – 2x)] = 8

By cross multiplication, we get

(5(1 – x)) + (3(1 + x)) = 8 × (1 – 2x)

5 – 5x + 3 + 3x = 8 – 16 x

8 – 2x = 8 – 16x

Transposing 8 to RHS it becomes – 8 and -16x to LHS it becomes 16x.

16x – 2x = 8 – 8

14x = 0

x = 0/14

x = 0
