-2x-6x+12=-x+3-6
Use the distributive property to multiply -3 by 2x-4.
-8x+12=-x+3-6
Combine -2x and -6x to get -8x.
-8x+12=-x-3
Subtract 6 from 3 to get -3.
-8x+12+x=-3
Add x to both sides.
-7x+12=-3
Combine -8x and x to get -7x.
-7x=-3-12
Subtract 12 from both sides.
-7x=-15
Subtract 12 from -3 to get -15.
x=\frac{-15}{-7}
Divide both sides by -7.
x=\frac{15}{7}
Fraction \frac{-15}{-7} can be simplified to \frac{15}{7} by removing the negative sign from both the numerator and the denominator.
