Jayne stopped to get gas before going on a road trip. the tank already had 4 gallons in it. which equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x

answer:

y=5

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
