Question

Mary, Rafael, and Goran sent a total of 119 text messages over their cell phones during the weekend. Goran sent 3 times as many messages as Mary. Mary sent 6 more messages than Rafael. How many messages did they each send?

Answer 1

M + R + G = 119
G = 3M
M = R + 6 —> R = M - 6

1st equation: M + (M-6) + (3M) = 119
5M -6 = 119
5M = 125

M = 25
G = 3(25) = 75
R = (25) -6 = 19
