3%284x%2B4%29=2%285x%2B9%29-12 Start with the given equation.


12x%2B12=10x%2B18-12 Distribute.


12x%2B12=10x%2B6 Combine like terms on the right side.


12x=10x%2B6-12 Subtract 12 from both sides.


12x-10x=6-12 Subtract 10x from both sides.


2x=6-12 Combine like terms on the left side.


2x=-6 Combine like terms on the right side.


x=%28-6%29%2F%282%29 Divide both sides by 2 to isolate x.


x=-3 Reduce.
