X=15
Move 4x to the left side and change side.Then move 3 to the right and change it’s sign.
3x-4x=-12-3
Combine like terms
-x=-15
Multiply each side by -1

x=15

Step 1: Subtract 4x from both sides.

3x+3−4x=4x−12−4x

−x+3=−12

Step 2: Subtract 3 from both sides.

−x+3−3=−12−3

−x=−15

Step 3: Divide both sides by -1.

−x−1=−15−1
