Answer:
175 Miles has to be driven to do the plans cost the same.
Step-by-step explanation:
Assume The Chau Drive Y miles .
We Have Given Two Plans ,
- First Plan = 50$ + 0.19$ × Y
- Second Plan = 57$ + 0.15$ × Y
Now,Put First Plan=Second Plan (When Both Plans Cost The Same)
50$ + 0.19$ × Y = 57$ + 0.15$ × Y
0.04$ × Y = 7 ⇔ Y = 175 Miles
Let’s put the second equation on top
3x + 4y = 1
-3x + 2y = -13
I’m subtracting the first eqautionfrom the second
2y = 14
Y= 7
Plug in 7 for y in either of the original equations
3x + 28 = 1
3x = -27
X= -9
The answer is (-9,7)
