2-5x-3x=-9
Subtract 3x from both sides.
2-8x=-9
Combine -5x and -3x to get -8x.
-8x=-9-2
Subtract 2 from both sides.
-8x=-11
Subtract 2 from -9 to get -11.
x=\frac{-11}{-8}
Divide both sides by -8.
x=\frac{11}{8}
Fraction \frac{-11}{-8} can be simplified to \frac{11}{8} by removing the negative sign from both the numerator and the denominator.
