Answer: 5


Procedure:
Our first objective is to get x alone, but because it is trapped in between the parentheses, we’ve gotta negate the “1/2”. To do this, you multiply both sides by to, which now gives you (3 + x = 8). Now, 1 step away from getting x, we have to subtract 3 from both sides, so x is alone and 8 minus 3 is 5.

So though thee steps, we get an answer of x = 5
