Subtract 4 from both sides:


-5(3x - 4) = 110

There is a coefficient for the term in parentheses: -5. To get rid of this coefficient, divide both sides by -5:


3x - 4 = -22

Add 4 to both sides:


3x = -18

Divide both sides by 3 to get x by itself:


\boxed{x = -6}

-5 * (3x - 4) + 4= 114

-15x +20 + 4 = 114

-15x = 114 - 24

-15x = 90

x = 90 : (-15)

x = -6
