Question

Justin has $7.50 more than Ava and Emma has $12 less than Justin together they have a total of $63 how much does each person have

Answer 1

J is Justin, A is Ava, and E is Emma.

J=7.50 + A or A=J-7.50
J=E +12 or E=J-12

J + J-7.50 + J-12=63
3J - 19.50 =63
3J = 82.50
J= 27.5

So.. J=27.50, E=15.50, and A=20.00

Justin has $27.50, Emma has $15.50, and Ava has $20.00

Answer 2

In the future, please use commas and periods. It was difficult to decipher where each equation started and ended.
J = Justin
A = Ava
E = Emma
J = A + 7.50
E = J - 12
E + J + A = 63
E = A + 7.50 - 12
A + A - 4.5 + A + 7.50 = 63
3A = 60
A = $20
J = $27.50
E = $15.50
