\frac{0.14}{0.15}=1-0.3x
Divide both sides by 0.15.
\frac{14}{15}=1-0.3x
Expand \frac{0.14}{0.15} by multiplying both numerator and the denominator by 100.
1-0.3x=\frac{14}{15}
Swap sides so that all variable terms are on the left hand side.
-0.3x=\frac{14}{15}-1
Subtract 1 from both sides.
-0.3x=\frac{14}{15}-\frac{15}{15}
Convert 1 to fraction \frac{15}{15}.
-0.3x=\frac{14-15}{15}
Since \frac{14}{15} and \frac{15}{15} have the same denominator, subtract them by subtracting their numerators.
-0.3x=-\frac{1}{15}
Subtract 15 from 14 to get -1.
x=\frac{-\frac{1}{15}}{-0.3}
Divide both sides by -0.3.
x=\frac{-1}{15\left(-0.3\right)}
Express \frac{-\frac{1}{15}}{-0.3} as a single fraction.
x=\frac{-1}{-4.5}
Multiply 15 and -0.3 to get -4.5.
x=\frac{-10}{-45}
Expand \frac{-1}{-4.5} by multiplying both numerator and the denominator by 10.
x=\frac{2}{9}
Reduce the fraction \frac{-10}{-45} to lowest terms by extracting and canceling out -5.
