4x%2B7=2%28x-3%29 Start with the given equation.


4x%2B7=2x-6 Distribute.


4x=2x-6-7 Subtract 7 from both sides.


4x-2x=-6-7 Subtract 2x from both sides.


2x=-6-7 Combine like terms on the left side.


2x=-13 Combine like terms on the right side.


x=%28-13%29%2F%282%29 Divide both sides by 2 to isolate x.

Answer:

So the solution is x=-13%2F2 which in decimal form is x=-6.5.
