# 1


3%284x-7%29=2%287x%2B13%29 Start with the given equation.


12x-21=14x%2B26 Distribute.


12x=14x%2B26%2B21 Add 21 to both sides.


12x-14x=26%2B21 Subtract 14x from both sides.


-2x=26%2B21 Combine like terms on the left side.


-2x=47 Combine like terms on the right side.


x=%2847%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=-47%2F2 Reduce.

Answer:

So the solution is x=-47%2F2
