-15-1.5x-3.6x=51.3
Subtract 3.6x from both sides.
-15-5.1x=51.3
Combine -1.5x and -3.6x to get -5.1x.
-5.1x=51.3+15
Add 15 to both sides.
-5.1x=66.3
Add 51.3 and 15 to get 66.3.
x=\frac{66.3}{-5.1}
Divide both sides by -5.1.
x=\frac{663}{-51}
Expand \frac{66.3}{-5.1} by multiplying both numerator and the denominator by 10.
x=-13
Divide 663 by -51 to get -13.
