Answer:
Jerry collected 126 stamps.
Renee collected 487 stamps.
Step-by-step explanation:
Let Jerry be J and Renee be R
Eq1: R=4J-17
Eq2: 613=R+J
Rearrange the second equation to isolate J:
J=613-R
Sub this new equation into Eq1 and solve for R:
R=4(613-R)-17
R=2452-4R-17
5R=2435
R=487
Sub R=487 into Eq2 to solve for J
613=487+J
J=126
