5x-3 (5x+10) - 14=82-128

x=1/5

Step-by-step explanation:

5x-3 (5x+10) - 14=82-128

Simplify the right side; 82-128=-46

5x-3 (5x+10) - 14=-46

Add 14 to both side to rid the variable side from the constant.

5x-3 (5x+10) = -32

Distribute the - 3 over to the parenthesis.

5x-15x-30=-32

Combine like terms

-10x-30=-32

Add 30 to both sides to rid the variable of the constant.

-10x=-2

Divide both sides of the equation by - 10 to isolate the variable

You are left with x=1/5
