<pre>

To isolate x, move term 5x from the left side to the right side, changing the sign to opposite one;


at the same time move the term (-1) from the right side to the left side, changing its sign to the opposite one.


Then you get this equivalent equation


    3 + 1 = 7x - 5x


and "isolation" is completed.
