Is it a multiple choice question? I mean, 10/80?..
To solve for y you need to first multiply both sides by 4. This will give you: 4y - 4A / 3 = A + 3B
Next you need to multiply both sides by 3: 4y - 4A = 3A + 9B
Now you need to add 4A to both sides: 4y = 7A + 9B
Now divide both sides by 4:
Y = 7A/4 + 9B/4
