Question

What makes this equation true?

Answer 1

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
