x-12=\frac{420}{25}
Divide both sides by 25.
x-12=\frac{84}{5}
Reduce the fraction \frac{420}{25} to lowest terms by extracting and canceling out 5.
x=\frac{84}{5}+12
Add 12 to both sides.
x=\frac{84}{5}+\frac{60}{5}
Convert 12 to fraction \frac{60}{5}.
x=\frac{84+60}{5}
Since \frac{84}{5} and \frac{60}{5} have the same denominator, add them by adding their numerators.
x=\frac{144}{5}
Add 84 and 60 to get 144.
