Step-by-step explanation:

First, move +7 to the other side of equation on the answer side and change it to it's absolute (in this case I mean negative) value:

3x + x = 13 - 7

Next, Simplify the equation:

4x = 6

Finally, Celebrate! You just (hopefully) learned how to solve this!

x = 1.5

or

x = [tex]\frac{1}{2}[/tex]
