0.3x+1377=1581
Combine 1.2x and -0.9x to get 0.3x.
0.3x=1581-1377
Subtract 1377 from both sides.
0.3x=204
Subtract 1377 from 1581 to get 204.
x=\frac{204}{0.3}
Divide both sides by 0.3.
x=\frac{2040}{3}
Expand \frac{204}{0.3} by multiplying both numerator and the denominator by 10.
x=680
Divide 2040 by 3 to get 680.
