Simplify both sides of the equation
Subtract 2 from both sides
Divide both sides by 5


OR

Answer:
5km costs $4
if you take the intial charge of $2, you're paying $4 per 5km
hence 10km= 2 *5km= 2*$4=$8+initial charge $2= $10
15Km= 3*5km= 3*$4= $12 + intial charge $2 = $14
Step-by-step explanation:
The answer should be
Y=-3x+19
46+19+54= 119, so the answer is 119
