Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas 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? y=4+x
y = x − 4
y = 4 · x
y = x ÷ 4

Step-by-step explanation:

Given: The tank already had 4 gallons of gas in it.

y denotes the total amount of gasoline in the tank.

x denotes the number of gallons that is put in the tank

To choose: the correct option

Solution:

Total number of gallons = y

Total number of gallons =

According to question,

so then what are you asking?

step-by-step explanation:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
