5-3x=8+9-7
Combine -6x and 3x to get -3x.
5-3x=17-7
Add 8 and 9 to get 17.
5-3x=10
Subtract 7 from 17 to get 10.
-3x=10-5
Subtract 5 from both sides.
-3x=5
Subtract 5 from 10 to get 5.
x=\frac{5}{-3}
Divide both sides by -3.
x=-\frac{5}{3}
Fraction \frac{5}{-3} can be rewritten as -\frac{5}{3} by extracting the negative sign.
