3+2x-30=78-3x
Use the distributive property to multiply 2 by x-15.
-27+2x=78-3x
Subtract 30 from 3 to get -27.
-27+2x+3x=78
Add 3x to both sides.
-27+5x=78
Combine 2x and 3x to get 5x.
5x=78+27
Add 27 to both sides.
5x=105
Add 78 and 27 to get 105.
x=\frac{105}{5}
Divide both sides by 5.
x=21
Divide 105 by 5 to get 21.
