3x - 4 - 5x = x + 4 + x

Simplify both sides of the equation.

3x−4−5x=x+4+x

3x+−4+−5x=x+4+x

(3x+−5x)+(−4)=(x+x)+(4)(Combine Like Terms)

−2x+−4=2x+4

−2x−4=2x+4

Subtract 2x from both sides.

−2x−4−2x=2x+4−2x

−4x−4=4

Add 4 to both sides.

−4x−4+4=4+

−4x=8

-Divide both sides by -4.

−4x/−4 = 8/−4

x = −2
