take the equations and replace the variables accordingly with x and y;
5s + 10a = 3000
x = students
y = adults
5x + 10y = 3000
follow the instructions to find x/y intercept;
for example;
5(0) + 10y = 3000
10y = 3000
y = 300;
you would then want to solve for “x” by plugging “y” for 0.
I can explain further if you’d like;
