Question

What is the solution to the proportion? Start Fraction 3 y minus 8 over 12 End fraction equals start fraction y over 5 End Fraction?

Answer 1

We have that

(3y-8)/12=(y/5)---------> 5*(3y-8)=12*(y)
15y-40=12y-------------> 15y-12y=40
3y=40--------------> y=40/3

y=(40/3)----------> 13.33

the answer is y=40/3  (13.33)
