Chapter A.6, Problem 26AYU

To determine

To solve: $5-\left(2x-1\right)=10$

Answer to Problem 26AYU

$x=-2$

Explanation of Solution

$5-\left(2x-1\right)=10$

$5-2x+1=10$

$6-2x=10$

$6-2x-6=10-6$   (Subtract 6 on both sides)

$-2x=4$

$\frac{-2x}{-2}=\frac{4}{-2}$   (Divide $-2$ on both sides)

$x=-2$
