Question

Jerry and Renee collect stamps. Renee collected 17 fewer than four times the number of Jerry’s stamps. Altogether, they collected 613 stamps. How many stamps did Jerry and Renee collect?
Jerry collected ______ stamps.
Renee collected _______stamps.

Answer 1

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
