-2%284x%2B5%29=8x%2B10 Start with the given equation.


-8x-10=8x%2B10 Distribute.


-8x=8x%2B10%2B10 Add 10 to both sides.


-8x-8x=10%2B10 Subtract 8x from both sides.


-16x=10%2B10 Combine like terms on the left side.


-16x=20 Combine like terms on the right side.


x=%2820%29%2F%28-16%29 Divide both sides by -16 to isolate x.


x=-5%2F4 Reduce.

Answer:

So the solution is x=-5%2F4
