4x%2B7%28x-7%29=6x-19 Start with the given equation.


4x%2B7x-49=6x-19 Distribute.


11x-49=6x-19 Combine like terms on the left side.


11x=6x-19%2B49 Add 49 to both sides.


11x-6x=-19%2B49 Subtract 6x from both sides.


5x=-19%2B49 Combine like terms on the left side.


5x=30 Combine like terms on the right side.


x=%2830%29%2F%285%29 Divide both sides by 5 to isolate x.


x=6 Reduce.
