0.3x=0.03-0.12
Subtract 0.12 from both sides.
0.3x=-0.09
Subtract 0.12 from 0.03 to get -0.09.
x=\frac{-0.09}{0.3}
Divide both sides by 0.3.
x=\frac{-9}{30}
Expand \frac{-0.09}{0.3} by multiplying both numerator and the denominator by 100.
x=-\frac{3}{10}
Reduce the fraction \frac{-9}{30} to lowest terms by extracting and canceling out 3.
