What are the two equations we can make ? One is about the price,the other is the total rentals

Question

They charge $2 for each video game, and $1 for each rented movie . Last week the total number of rentals was 114 and the machine made a total $177 how many movies were rented?

Answer 1

2V + R =177

V + R = 114 subtract 2nd equation from the 1st to eliminate one variable to get:

V = 63 videos

R = 114 -63 = 51 rented movies

Answer 2

2V + R =177

V + R = 114 subtract 2nd equation from the 1st to eliminate one variable to get:

V = 63 videos

R = 114 -63 = 51 rented movies
