Answer:


B.\cfrac{1}{2}

Given equation


  • \cfrac{12y-1}{2} =\cfrac{9y+8}{5}

Solve it for y

1. Cross - multiply:


  • 5(12y-1)=2(9y+8)

2. Open parenthesis:


  • 60y-5=18y+16

3. Collect like terms:


  • 60y-18y=16+5

4. Simplify:


  • 42y=21

5. Divide both sides by 42:


  • y=21/42=1/2

Matching answer choice is B
