5.1x+3.2-1.2x=-4.6
Subtract 1.2x from both sides.
3.9x+3.2=-4.6
Combine 5.1x and -1.2x to get 3.9x.
3.9x=-4.6-3.2
Subtract 3.2 from both sides.
3.9x=-7.8
Subtract 3.2 from -4.6 to get -7.8.
x=\frac{-7.8}{3.9}
Divide both sides by 3.9.
x=\frac{-78}{39}
Expand \frac{-7.8}{3.9} by multiplying both numerator and the denominator by 10.
x=-2
Divide -78 by 39 to get -2.
