Let's named variables as M,J and R
The equation is M+J+R=74
We will represent M with J => M=J+6 and R=2J
when we replace in the equation we get
J+6+J+2J=74 => 4J=74-6 => 4J=68 => J=68/4 = 17
J=17 => M=6+17 => M=23 and R=2* 17 => R=34
Final answer is
Juan served 17 orders
Melissa served 23 orders and
Rafael served 34 orders
Good luck!!!!
First you put 2.13 on top of a fraction and 36 on the bottom. Then you divide 36 by 2.13 and put the answer, 16.90, on top of another fraction and put a 1 on the bottom of that other fraction.
