Question

Between them Molly and Sue have 32 marbles. Molly has 3 times as many as Sue. How many marbles does each girl have?

Answer 1

Sue has 8 marbles

Molly has 8 marbles

Explanation:

m = number of marbles Molly has

s = number of marbles that sue has

m+s =32

m = 3s

Substitute the second equation into the first equation

3s+s =32

4s = 32

Divide by 4

4s/4 =32/4

s = 8

Sue has 8 marbles

m = 32 = 3*8 = 24

Molly has 8 marbles
