2%2810%2B7x%29=-36 Start with the given equation.


20%2B14x=-36 Distribute.


14x=-36-20 Subtract 20 from both sides.


14x=-56 Combine like terms on the right side.


x=%28-56%29%2F%2814%29 Divide both sides by 14 to isolate x.


x=-4 Reduce.

Answer:

So the solution is x=-4



===========================================================================

-79=-5x-4x%2B2 Start with the given equation.


-79=-9x%2B2 Combine like terms on the right side.


0=-9x%2B2%2B79 Add 79 to both sides.


9x=2%2B79 Add 9x to both sides.


9x=81 Combine like terms on the right side.


x=%2881%29%2F%289%29 Divide both sides by 9 to isolate x.


x=9 Reduce.

Answer:

So the solution is x=9
