1.5x-0.3+2x=0.4
Add 2x to both sides.
3.5x-0.3=0.4
Combine 1.5x and 2x to get 3.5x.
3.5x=0.4+0.3
Add 0.3 to both sides.
3.5x=0.7
Add 0.4 and 0.3 to get 0.7.
x=\frac{0.7}{3.5}
Divide both sides by 3.5.
x=\frac{7}{35}
Expand \frac{0.7}{3.5} by multiplying both numerator and the denominator by 10.
x=\frac{1}{5}
Reduce the fraction \frac{7}{35} to lowest terms by extracting and canceling out 7.
