4x%2B13=-9-3%28x%2B9%29 Start with the given equation.


4x%2B13=-9-3x-27 Distribute.


4x%2B13=-3x-36 Combine like terms on the right side.


4x=-3x-36-13 Subtract 13 from both sides.


4x%2B3x=-36-13 Add 3x to both sides.


7x=-36-13 Combine like terms on the left side.


7x=-49 Combine like terms on the right side.


x=%28-49%29%2F%287%29 Divide both sides by 7 to isolate x.


x=-7 Reduce.
