Answer:
Step-by-step explanation: emma's amount be X . justin has $7.50+x because he has $7.50 more than emma.Since emma has 7.50+x-$12.to get everyones amount add what they have together which is=$7.50+x+$7.50+x-12 which in total is $63.00.after the calculations you get x=30.now distribute the x equally. so justin has $7.50+30=37.50.we also distribute it with emma's which is 7.50+30-12=25.5.
justin=$37.50
Emma=$25.50
to be sure add 37.50+25.50=$63
Answer:
n=4p
Step-by-step explanation:
18n-7p-15n=5p
3n-7p=5p
3n=5p+7p
3n=12p
n=12p/3
n=4p
we need the equation or graph to figure that out
