Ok im not sure the answer yet so ima work on it at the same time while im explaining it. (The answer will probably be near the end)
We can use the elimination method to eliminate y out. To do that we multiply the first equation by 3.
6x+3y=-12
Now just subtract it from the other equation.
6x+3y=-12
5x+3y=-6
***x=-6***
Usually after doing the elimination method you will have to solve for x but in this case its already solved for you. If you want to find y now you just take the first equation and fill x with -6 and solve for y.
2(-6)+y=-4
-12+y=-4
y=8

Answer:
(a) x: Ferris wheel once; y: roller coaster once
Step-by-step explanation:
The coefficients of x and y are both 1 in the equation representing the statement ...
"if he rides them each once, it takes 14 minutes total."
That tells you that x and y represent the times for one ride.
__
The coefficient of x is 6 in the equation representing the statement ...
"he rides the Ferris wheel 6 times ..."
This tells you the variable x represents the Ferris wheel ride time. It is further confirmation that x represents the time for one ride.
This is written in slope intercept form, or y=mx+b, where m is slope and b is y intercept. Just look at the values that represent m and b to find the answer.
Slope: 3/4
Y intercept: -4
