0.4+0.03x-2.1=0.5
Use the distributive property to multiply x-70 by 0.03.
-1.7+0.03x=0.5
Subtract 2.1 from 0.4 to get -1.7.
0.03x=0.5+1.7
Add 1.7 to both sides.
0.03x=2.2
Add 0.5 and 1.7 to get 2.2.
x=\frac{2.2}{0.03}
Divide both sides by 0.03.
x=\frac{220}{3}
Expand \frac{2.2}{0.03} by multiplying both numerator and the denominator by 100.
