To isolate x you would start by subtracting 1/2 from both sides and be left with 1/5x= 7/2, then you would multiply both sides by 5 to get rid of 1/5 and you would be left with x=35/2
First let's get rid of the in the denominator of the fraction on the right side of the equation. This will help to get only and a coefficient on one side of the equation:
