25y-50=2\times 80
Multiply both sides of the equation by 200, the least common multiple of 8,100.
25y-50=160
Multiply 2 and 80 to get 160.
25y=160+50
Add 50 to both sides.
25y=210
Add 160 and 50 to get 210.
y=\frac{210}{25}
Divide both sides by 25.
y=\frac{42}{5}
Reduce the fraction \frac{210}{25} to lowest terms by extracting and canceling out 5.
