12-x-x=-3
Subtract x from both sides.
12-2x=-3
Combine -x and -x to get -2x.
-2x=-3-12
Subtract 12 from both sides.
-2x=-15
Subtract 12 from -3 to get -15.
x=\frac{-15}{-2}
Divide both sides by -2.
x=\frac{15}{2}
Fraction \frac{-15}{-2} can be simplified to \frac{15}{2} by removing the negative sign from both the numerator and the denominator.
