1st statement
Justin has 7.5 more than Eva 7.5+E
Eva = E
2nd statement
Emma has 12 less than Justin J - 12
when J= Justin = 7.5 + E
last statement
Eva+Justin+Emma = 63
E + (7.5+E) + (7.5+E-12) =63
ADD UP
3E + 15 - 12 = 63
3E + 3 = 63
3E=63 - 3
3E=60
E=20 EMMA receives 20
J=7.5+20
J=27.5 JUSTIN receives 27.5
M=J-12
M=27.5-12
M=15.5 EMMA receives 15.5
