Answer:
x - y = - 1
Step-by-step explanation:
Given the 2 equations
5x + 4y = 13 → (1)
4x + 5y = 14 → (2)
Subtract (2) from (1) term by term , that is
(5x - 4x) + (4y - 5y) = 13 - 14
x - y = - 1

The answer is <u><em>40 miles</em></u>.
First you have to put it into an equation. When you do this you get .90x+2+3.50=41.50
Now you have to solve using inverse operation. Subtract 3.50 from 41.50 and you get 38.00. Now your equation is .90x+2=38.00
Now you have to subtract 2 form 38.00 and you get 36.00. Now you get .90x=36.00
Then you have to divide 36.00 by .90 and you get <u><em>40</em></u>. Therefore <u><em>x=40</em></u>, which means you can travel <u><em>40</em></u> miles.
