The answer to this question is D) 1/2.
How to solve this:
Step 1: Cross-multiply.
12y-1/2 = 9y+8/5
(12y - 1) * (5) = (9y + 8) * (2)
60y - 5 = 18y + 16
Step 2: Subtract 18y from both sides.
60y - 5 - 18y = 18y + 16 -18y
42y − 5 = 16
Step 3: Add 5 to both sides.
42y - 5 + 5 = 16 + 5
42y = 21
Step 4: Divide both sides by 42.
42y/42 = 21/42
y = 1/2
