8x-6-5x=12x-2
Use the distributive property to multiply 2 by 4x-3.
3x-6=12x-2
Combine 8x and -5x to get 3x.
3x-6-12x=-2
Subtract 12x from both sides.
-9x-6=-2
Combine 3x and -12x to get -9x.
-9x=-2+6
Add 6 to both sides.
-9x=4
Add -2 and 6 to get 4.
x=\frac{4}{-9}
Divide both sides by -9.
x=-\frac{4}{9}
Fraction \frac{4}{-9} can be rewritten as -\frac{4}{9} by extracting the negative sign.
