20000\left(1+\frac{x}{100}\right)\times 2=22472
Multiply both sides of the equation by 100.
40000\left(1+\frac{x}{100}\right)=22472
Multiply 20000 and 2 to get 40000.
40000+40000\times \frac{x}{100}=22472
Use the distributive property to multiply 40000 by 1+\frac{x}{100}.
40000+400x=22472
Cancel out 100, the greatest common factor in 40000 and 100.
400x=22472-40000
Subtract 40000 from both sides.
400x=-17528
Subtract 40000 from 22472 to get -17528.
x=\frac{-17528}{400}
Divide both sides by 400.
x=-\frac{2191}{50}
Reduce the fraction \frac{-17528}{400} to lowest terms by extracting and canceling out 8.
