Question

Martina, Brian, and Austin sent a total of 92 text messages over their cell phones during the weekend. Austin sent 8 more messages than Martina. Brian sent 2 times as many messages as Austin. How many messages did they each send?

Answer 1

Make Martina as x, then austin is x＋8, brian is 2(X＋8). X＋(X＋8)＋2(X＋8)＝92,
4x＝92-8-16,
X＝17
M is 17, A is 25, B is 50
