Because we are looking at money and amount there will be 2 sepret equations that can be solved using the Elimination or Substitution method.
$4,800=x18+y33 would be the first one that is dealing with money.
200=x+y
I personally find the substitution method easier but whatever you like could work. First things first, get Y alone in ONE equation, you can choose whatever one you want but I am going to use the bottom one cause it is the easiest.
200=x+y
-x -x subtract x from both sides
200-x=y. y is now alone making it easy to switch the equation
y=200-x this equation is the value of y
Now plug in the value of y in the top equation,
4,800=x18+33(200-x) now solve this equation
4,800=x18+6600-33x
4,800=-15x+6600
-6600. -6600
-2200=-15x. divide by -15
x=146.67
now since we have the x value we can plug it in to the bottom equation.
200=146.67+y
-146.67
y=53.33
these coordinates are the intersection point so it'll give ya the number.
hope this helped a little
