Question

Blank x – 8 = – 2 ( – x – 13 )

Answer 1

x = -34

Explanation:

x – 8 = – 2 ( – x – 13 )

multiply right side out:

x – 8 = 2x + 26

add 8 to both sides:

x – 8 + 8 = 2x + 26 + 8

x = 2x + 34

subtract 2x from both sides:

x - 2x = 2x + 34 - 2x

-x = 34

divide both sides by -1:

-x/-1 = 34/-1

x = -34

Answer 2

`x - 8 = - 2( - x - 13) \\ \\ \longrightarrow \: x - 8 = 2x + 26 \\ \\ \longrightarrow \: 2x - x = - 8 - 26 \\ \\ \longrightarrow \:\boxed{ x = - 34}`
