If it is #17 this:
the class sold 45 sandwiches and collected $150.75, all you need to do is divide.
150.75/45
= 3.35
$3.35 per sandwitch
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Just draw one empty circle for 1 and then a filled circle for -1 so then it's 1-1 which equals 0
