21+27+3x=7+9+x
Multiply both sides of the equation by 3.
48+3x=7+9+x
Add 21 and 27 to get 48.
48+3x=16+x
Add 7 and 9 to get 16.
48+3x-x=16
Subtract x from both sides.
48+2x=16
Combine 3x and -x to get 2x.
2x=16-48
Subtract 48 from both sides.
2x=-32
Subtract 48 from 16 to get -32.
x=\frac{-32}{2}
Divide both sides by 2.
x=-16
Divide -32 by 2 to get -16.
