How do you solve 12-2(x-5)=20?

May 2, 2018

Explanation:

$12 - 2 \left(x - 5\right) = 20$

$12 - 2 x + 10 = 20$

$- 2 x + 22 = 20$

$- 2 x = 20 - 22$

$- 2 x = - 2$

$x = \frac{- 2}{- 2}$

$x = 1$

This is your answer: $x = 1$.

$x = 1$

Explanation:

open the brackets and then simplify the equation first.
$12 - 2 \left(x - 5\right) = 20$
$12 - 2 x + 10 = 20$
$22 - 2 x = 20$
$- 2 x = 20 - 22$
$- 2 x = - 2$
$x = - \left(- \frac{2}{2}\right)$
$x = 1$
$12 - 2 \left(1 - 5\right)$
$12 - 2 \left(- 4\right)$
$12 - \left(- 8\right)$
$12 + 8 = 20$
