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

-15x +20 + 4 = 114

-15x = 114 - 24

-15x = 90

x = 90 : (-15)

x = -6

Subtract 4 from both sides:

[tex]-5(3x - 4) = 110[/tex]

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

[tex]3x - 4 = -22[/tex]

Add 4 to both sides:

[tex]3x = -18[/tex]

Divide both sides by 3 to get x by itself:

[tex]\boxed{x = -6}[/tex]
