Question

8 – ( 5 – 9x ) = 7( 1 – x )​

Answer 1

8 - (5 - 9x) = 7(1 - x)

8 - 5 + 9x = 7 - 7x

3 + 9x = 7 - 7x

3 + 16x = 7

16x = 4

x = 4/16

0.25

Explanation:

Answer 2

x =
`(1)/(4)`

Explanation:

Given

8 - (5 - 9x) = 7(1 - x) ← distribute parenthesis on both sides

8 - 5 + 9x = 7 - 7x

3 + 9x = 7 - 7x ( add 7x to both sides )

3 + 16x = 7 ( subtract 3 from both sides )

16x = 4 ( divide both sides by 16 )

x =
`(4)/(16)` =
`(1)/(4)`
