Best Answer

12y - 9 = 21 : Add 9 to both sides

12y = 30 : Divide both sides by 12

y = 30/12 = 2.5 or 21/2.

The equation is 12y - 9 = 21. To solve for y, you can start by adding 9 to both sides to isolate the term with y. This gives you 12y = 30. Next, divide both sides by 12 to solve for y, which gives y = 2.5.
