You and a friend go to a mexican restaurant. you order 2 tacos and 3 enchiladas and your friend orders 3 tacos and 5 enchiladas.
Eva8 [605]
For this case, the first thing we must do is define variables.
 We have then:
 x: cost of tacos
 y: cost of enchiladas.
 We write the system of equations:
 2x + 3y = 7.80
 3x + 5y = 12.70
 Solving the system we have:
 x = 0.9 $
 y = 2 $
 Answer:
 
each taco and each enchilada was:
 
x = 0.9 $
 
y = 2 $
