By substitution is how to solve
2x-3y=21
y=3-x
2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6
now substitute our x value into y=3-x
so we get
y=3-6 = -3
so x=6 and y=-3 hope this helps!!!!! Thank you!
Answer:
$65.07
Step-by-step explanation:
We know in this problem they charge a $19.95 fee plus the total number of miles.
0.24 times 188 = 42.12 that´s only for the miles then the rental fee
