Question 457281
let x = the number of 2-point baskets Anya made
    y = the number of 3-point baskets Anya made

Equations:
x + y = 14
2x + 3y = 30
------------------------
Multiply the 1st equation by 3 to get:
3x + 3y = 42

Subtract above equation by 2nd equation to get:
(3x-2x) + (3y - 3y) =  42 -30
x = 12

Anya made 12 2-point baskets.
