The equation will be 2.05+.90x=5.65

X equals each mile so we need to get x alone to find how many miles the trips was.
First subtract 2.05 from both sides of the equation.

0.90x=3.60
Then divide both sides by 0.90
x=4
The trip was four miles.
so you do,

5.65-2.05 which is 3.6

Then 3.6/.90 which is 4 miles/.
