20+2x=3x subtract 2x from both sides
20=x after 20 miles the total cost for both companies will be the same
PROOF
20+2(20)=3(20)
20+40=60
60=60
Add 10 to both sides, so you get v=1
Step-by-step explanation:

<span>Input (x) [-2.7] [-1.3] [0.8] [4.4]
Output f(x) [-5.25] [-1.75] [3.5] [12.5]
Input (x) [1.1] [2.4] [5.3] [6.9]
Output f(x) [4.25] [7.5] [11.75] [17.25]
Input (x) [-2.1] [0.9] [1.7] [3.3]
Output f(x) [-3.75] [3.75] [5.75] [9.75]
Just substitute the inputs for x.
