Answer:

x = [tex]\frac{1}{4}[/tex]

Step-by-step 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 = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

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
