The answer is x=3x=3.

Explanation:

First, you must isolate the variables by one of the xx to the other side(do not forget to change it to a negative if a positive or vice-versa). Then just isolate the variable by changing the numbers to one side and the variables on the other side. It should give you an equation like

5x-x=5+75xx=5+7

which equals

4x=124x=12

then just divide both sides by 44.

(4x)/4 = 12/44x4=124

So

x=3x=3
