The equation given below shows this relationship, where x represents the number of marbles Beth has, and y represents the number of marbles Amy has.

Question

x=4y

If Beth has 48 marbles, how many marbles does Amy have?

Answer 1

If x = 48, then we can substitute this value in the equation:

48 = 4y

To solve for y, we can divide both sides by 4:

48/4 = y

12 = y

Therefore, Amy has 12 marbles.
