Question

solve for x.
11 + 15x = -7 + 13x
simplify your answer as much as possible.

Explanation:

Step1: Move x - terms to one side

Subtract 13x from both sides.
$11 + 15x-13x=-7 + 13x-13x$
$11 + 2x=-7$

Step2: Move constant to the other side

Subtract 11 from both sides.
$11 + 2x-11=-7-11$
$2x=-18$

Step3: Solve for x

Divide both sides by 2.
$\frac{2x}{2}=\frac{-18}{2}$
$x = - 9$

Answer:

$x=-9$
