Raina, austin, goran sent a total of 95 text messages over their cell phones during the weekend. goran send 3 times as many messages as austin. austin sent 10 fewer messages than raina. how many messages did they each send?

R + A + G = 95lol...rag
G = 3A
A = R - 10

G = 3(R - 10)...G = 3R - 30

R + A + G = 95
R + (R - 10) + (3R - 30) = 95
5R - 40 = 95
5R = 95 + 40
5R = 135
R = 135/5
R = 27 <===Raini sent 27

A = R - 10
A = 27 - 10
A = 17 <===Austin sent 17

G = 3R - 30
G = 3(27) - 30
G = 81 - 30
G = 51 <==Goran sent 51
