Answer:

x=-5

Explanation:

22=-2x+4(-4x-17)

We move all terms to the left:

22-(-2x+4(-4x-17))=0

We calculate terms in parentheses: -(-2x+4(-4x-17)), so:

-2x+4(-4x-17)

We multiply parentheses

-2x-16x-68

We add all the numbers together, and all the variables

-18x-68

Back to the equation:

-(-18x-68)

We get rid of parentheses

18x+68+22=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

Answer:

Explanation:

22 = -2x + 4(-4x - 17)

22 = -2x + 4*(-4x) - 4*17

22 = -2x - 16x - 68 {Combine like terms}

22 = -18x - 68 {Add 68 to both sides}

22 + 68 = -18x

90 = -18x {Divide both sides by (-18)

90/-18 = x

x = -5
