Explanation:
first distribute the 2 on the left
8x+10 = 3x-25
subtract the 3x from both sides
5x+10 = -25
subtract 10 from both sides
5x = -35
divide both sides by 5 to solve for x
x = -7
check your answer by substituting into the original equation.
2(-28+5) = -21-25
distribute
-56+10 = -21-25
solve
-46 = -46
