jack paid $64 for two algebra and three geometry books. he paid $66 for three algebra and two geometry books. what is the cost o

kap26 [50]

Lets make the cost of the algebra textbook = x and the cost of the geometry book = y

2x+3y=64
4x+2y=66

now we get one of these equations in terms of one variable

2x+3y=64 ---> 2x=64-3y ---> x=32-1.5y

now we can plug that numeric value back into the other equation

4(32-1.5y)+2y=66

we can now simplify this equation in order to get the value of y

4(32-1.5y)+2y=66 ---> 128-6y+2y=66 ---> 128-4y=66 ---> -4y=-64 ---> y=16

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 $
