Question

Robert has seven more than five times the number of video games Sam has. All together they have 25 video games. How many video games does Robert have?

Answer 1

Explanation:

r = 5s + 7

r + s = 25

5s + 7 + s = 25

6s + 7 = 25

6s = 25 - 7

6s = 18

s = 18/6

s = 3 <=== sam has 3 video games

r = 5s + 7

r = 5(3) + 7

r = 15 + 7

r = 22 <=== robert has 22 video games
