First, you must isolate the variables by one of the x 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
$5x-x=5+7$
which equals
$4x=12$
then just divide both sides by 4.
$\frac{4x}{4}=\frac{12}{4}$
So
$x=3$
