You need to get x by itself. To do so you need to perform the opposite operations that are presented in the equation. Also, the operations furthest from the x should be done first.
In this case, there is only one operation (subtraction). To get x by itself we need to ADD 4 to both sides.
x = 11

Subtract the total from the factor that you know which is 4. so do 7 - 4 which equals 3. x=3
