Melissa, Deandre, and Ravi sent a total of 80 text messages over their cell phones during the weekend. Ravi sent 3 times as many messages as Deandre. Deandre sent 10 more messages than Melissa. How many messages did they each send?

OpenStudy (sw050399):

Make some equations and solve simultaneously!

OpenStudy (anonymous):

How? Guide me

OpenStudy (sw050399):

You're going to have 3 equations. M = Melissa, D = Deandre, R = Ravi. Together they sent 80 messages, so what would the equation be?

OpenStudy (anonymous):

Uhh M+D+R=Text ? @sw050399

OpenStudy (sw050399):

Yeah. First equation is M + D + R = 80. Now read the next line; Ravi send 3 times as many as Deandre. So what's the second equation?

OpenStudy (anonymous):

r(3d) ?

OpenStudy (anonymous):

R + 3D ?

OpenStudy (sw050399):

Ravi sent 3 times AS MANY as Deandre. There's an equal sign in there.

I'm confused still. brain is shot
