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

x = 1/5

Step-by-step explanation:

Given

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

Using the distributive property we have

5x - 3x5x + - 3x10 - 14 = 82-128

5x - 15x - 30 - 14 = - 46

-10x - 44 = - 46

Add 44 to both sides

-10x - 44+44 = - 46 + 44

-10x = - 2

Now divide both sides by - 10 to get the unknown x

-10x/-10 = - 2/-10

x = 1/5
