Question 334987
n = number of 2-point baskets
m = number of 3-point baskets

n + m = 11 >>>>> n = 11 – m 
2n + 3m = 26

2(11 – m) + 3m = 26
22 – 2m + 3m = 26
22 + m = 26
m = 26 – 22 = 4, so n = 11 – 4 = 7

Will made 4 2-point baskets and 7 3-point baskets for 26 points

Check this result in the original equation(s), I did!
