1.2x-3.6+0.3x=2.4
Add 0.3x to both sides.
1.5x-3.6=2.4
Combine 1.2x and 0.3x to get 1.5x.
1.5x=2.4+3.6
Add 3.6 to both sides.
1.5x=6
Add 2.4 and 3.6 to get 6.
x=\frac{6}{1.5}
Divide both sides by 1.5.
x=\frac{60}{15}
Expand \frac{6}{1.5} by multiplying both numerator and the denominator by 10.
x=4
Divide 60 by 15 to get 4.
