12y-20+5y>371
Use the distributive property to multiply 4 by 3y-5.
17y-20>371
Combine 12y and 5y to get 17y.
17y>371+20
Add 20 to both sides.
17y>391
Add 371 and 20 to get 391.
y>\frac{391}{17}
Divide both sides by 17. Since 17 is positive, the inequality direction remains the same.
y>23
Divide 391 by 17 to get 23.
