Answer:

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

Answer:

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
