Question

solve for x.
-3x + 7 = -9x + 49
simplify your answer as much as possible.
x =

Explanation:

Step1: Add 9x to both sides

$-3x + 9x+7=-9x + 9x+49$
$6x + 7=49$

Step2: Subtract 7 from both sides

$6x+7 - 7=49 - 7$
$6x=42$

Step3: Divide both sides by 6

$\frac{6x}{6}=\frac{42}{6}$
$x = 7$

Answer:

$7$
