Question

-9 (1 + 6x) = 42 - 3x

Answer 1

Answer:-1=x

Explanation:

-9(1+6x)=42-3x

-9-54x=42-3x

+54x +54x

-9=42+51x

-42 -42

-51/51=51x/51

-1=x

Answer 2

x = - 1

Explanation:

- 9(1 + 6x) = 42 - 3x ← distribute parenthesis on left side by - 9

- 9 - 54x = 42 - 3x ( add 3x to both sides )

- 9 - 51x = 42 ( add 9 to both sides )

- 51x = 51 ( divide both sides by - 51 )

x = - 1
