The solution to the equation is x=-2.
First simplify the equation by combining like terms.
3x-4-5x=x+4+x
Combine 3x+(-5x) and x+x.
3x+(-5x)=-2x
x+x=2x
-2x-4=2x+4
Subtract 2x from both sides of the equation.
-2x-2x-4=2x-2x+4
-4x-4=4
Add 4 on the sides of the equation.
-4x-4+4=4+4
-4x=8
Divide both sides by -4.
[tex] \frac{-4x}{4} [/tex]=[tex] \frac{8}{-4} [/tex]
x=-2
