Answer:

two rs coins = 36

five rs coins = 9

Step-by-step explanation:

number of two rs coin = x

number of five rs coin = y

2x + 5y = 117

x = 4y

2(4y) + 5y = 117

8y + 5y = 117

13y = 117

y = 117/13

y = 9

2x + 5y = 117

2x + 5(9) = 117

2x + 45 = 117

2x = 117 - 45

2x = 72

x = 72/2 = 36
