%281%2F2%29x-7=11-%281%2F2%29x Start with the given equation.


2%28%281%2Fcross%282%29%29x-7%29=2%2811-%281%2Fcross%282%29%29x%29 Multiply both sides by the LCD 2 to clear any fractions.


x-14=22-1x Distribute and multiply.


x=22-x%2B14 Add 14 to both sides.


x%2Bx=22%2B14 Add x to both sides.


2x=22%2B14 Combine like terms on the left side.


2x=36 Combine like terms on the right side.


x=%2836%29%2F%282%29 Divide both sides by 2 to isolate x.


x=18 Reduce.

Answer:

So the solution is x=18
