Question

solve the equation for x.
2(x + 10) = -2(x - 20)

Explanation:

Step1: Expand both sides

$2x + 20 = -2x + 40$

Step2: Add $2x$ to both sides

$2x + 2x + 20 = -2x + 2x + 40$
$4x + 20 = 40$

Step3: Subtract 20 from both sides

$4x + 20 - 20 = 40 - 20$
$4x = 20$

Step4: Divide by 4 on both sides

$\frac{4x}{4} = \frac{20}{4}$
$x = 5$

Answer:

$x=5$
