what is the soloution to the proportion 3y-8/12=y/5 and what is y

Answer 1

To solve the proportion 3y-8/12 = y/5 , we can cross multiply:

(3y - 8)(5) = 12y

15y - 40 = 12y

Subtract 12y from both sides:

15y - 12y - 40 = 0

3y - 40 = 0

Add 40 to both sides:

3y = 40

Divide both sides by 3:

y = 40/3

Therefore, the solution to the proportion is y = 40/3.
