\frac{1}{1+0.12}=1-2x
Multiply 0.06 and 2 to get 0.12.
\frac{1}{1.12}=1-2x
Add 1 and 0.12 to get 1.12.
\frac{100}{112}=1-2x
Expand \frac{1}{1.12} by multiplying both numerator and the denominator by 100.
\frac{25}{28}=1-2x
Reduce the fraction \frac{100}{112} to lowest terms by extracting and canceling out 4.
1-2x=\frac{25}{28}
Swap sides so that all variable terms are on the left hand side.
-2x=\frac{25}{28}-1
Subtract 1 from both sides.
-2x=\frac{25}{28}-\frac{28}{28}
Convert 1 to fraction \frac{28}{28}.
-2x=\frac{25-28}{28}
Since \frac{25}{28} and \frac{28}{28} have the same denominator, subtract them by subtracting their numerators.
-2x=-\frac{3}{28}
Subtract 28 from 25 to get -3.
x=\frac{-\frac{3}{28}}{-2}
Divide both sides by -2.
x=\frac{-3}{28\left(-2\right)}
Express \frac{-\frac{3}{28}}{-2} as a single fraction.
x=\frac{-3}{-56}
Multiply 28 and -2 to get -56.
x=\frac{3}{56}
Fraction \frac{-3}{-56} can be simplified to \frac{3}{56} by removing the negative sign from both the numerator and the denominator.
