Answer:
Jami has $13.5
Mami has $18.5
Step-by-step explanation:
Let j = Jami's money
m - Mami's money
j + m = 32
j = m - 5 (Since Jami basically has 5 less than Mami)
Substitute the j in the top equation
m - 5 + m = 32
2m - 5 = 32
Add 5 to both sides
2m - 5 = 32
2m = 37
Divide both sides by 2
2m/2 = 37/2
m = 37/2 = 18.5
Now plug the new m into the bottom equation
j = 18.5 - 5
j = 13.5
