Rewrite the equation below so that it does not have fractions.

Answer:

8x -24 = 9y

Step-by-step explanation:

We assume your equation is ...

2/3x -2 = 3/4y

__

Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.

LCM(3, 4) = 12

Multiplying the equation by 12 gives you ...

12(2/3x -2) = 12(3/4y)

8x -24 = 9y
