12+3x-8x=3
Subtract 8x from both sides.
12-5x=3
Combine 3x and -8x to get -5x.
-5x=3-12
Subtract 12 from both sides.
-5x=-9
Subtract 12 from 3 to get -9.
x=\frac{-9}{-5}
Divide both sides by -5.
x=\frac{9}{5}
Fraction \frac{-9}{-5} can be simplified to \frac{9}{5} by removing the negative sign from both the numerator and the denominator.
