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