4x-13+4-6x=12
Combine 3x and x to get 4x.
4x-9-6x=12
Add -13 and 4 to get -9.
-2x-9=12
Combine 4x and -6x to get -2x.
-2x=12+9
Add 9 to both sides.
-2x=21
Add 12 and 9 to get 21.
x=\frac{21}{-2}
Divide both sides by -2.
x=-\frac{21}{2}
Fraction \frac{21}{-2} can be rewritten as -\frac{21}{2} by extracting the negative sign.
