Question

if x-1/x+1 =7/9 then the value of x is

Answer 1

$\frac{x - 1}{x + 1 } = \frac{7}{9} \\ 9(x - 1) = 7( \times + 1) \\ 9x - 9 = 7x + 7 \\ 9x - 7x = 7 + 9 \\ 2x = 16 \\ x = 8$

Answer 2

Answer:

The value of x is 8

Step-by-step explanation:

x - 1 / x + 1 = 7/9

9(x - 1). = 7(x + 1)

9x -9. = 7x + 7

9x - 7x. = 7 + 9

2x = 16

x = 16/2

x = 8

Therefore the value of x is 8
