Answer 2

Step-by-step explanation:

Let x = number of free throws Susie made.

Let y = number of 2-point shots Susie made.

Let's make a system to represent this:

x + y = 10

x + 2y = 18 (every y shot makes 2 points, x shot makes 1 point)

By subtracting one equation from the other, we can cancel out the x. This is called "elimination".

x + y = 10

-x + 2y = 18

-y = -8

y = 8

Now, since these equations should be equal, you can plug 8 in for y in any of these equations to get x.

x + 8 = 10

x + 8 = 10

- 8 -8

x = 2

Set of solutions: x = 2; y = 8.

Remember from above, x represents the amount of free throws and y represents the amount of 2-point shots.

Sophie made 2 free throws and 8 two-point shots.
