Peter: P
Anthony: A
Peter played 4 more games than Anthony did
P=A+4
together they played 14 games.
P+A= 14
So, we have the system of equations:
P = A+4 (a)
P+A =14 (b)
Put (a) into (b)
(A+4)+A =14
Solve for A:
A+4 +A =14
2A+4 =14
2A=14-4
2A=10
A=10/2
A=5 (c)
(c) into (a)
P=A+4
P = 5+4
P=9
Anthony played 5 games
