-2x-\left(3x+4\right)=6
Multiply both sides of the equation by 2.
-2x-3x-4=6
To find the opposite of 3x+4, find the opposite of each term.
-5x-4=6
Combine -2x and -3x to get -5x.
-5x=6+4
Add 4 to both sides.
-5x=10
Add 6 and 4 to get 10.
x=\frac{10}{-5}
Divide both sides by -5.
x=-2
Divide 10 by -5 to get -2.
