0.4x-1.1-0.2x=0.3
Subtract 0.2x from both sides.
0.2x-1.1=0.3
Combine 0.4x and -0.2x to get 0.2x.
0.2x=0.3+1.1
Add 1.1 to both sides.
0.2x=1.4
Add 0.3 and 1.1 to get 1.4.
x=\frac{1.4}{0.2}
Divide both sides by 0.2.
x=\frac{14}{2}
Expand \frac{1.4}{0.2} by multiplying both numerator and the denominator by 10.
x=7
Divide 14 by 2 to get 7.
