Okay, now I'm good at all types of math, but I've been stuck on this problem for a while now: (BTW, this was under the section titled: "Using a System af Three Equations")

The sum of three numbers is 105. The third is 11 less than 10 times the second. Twice the first is 7 more than 3 times the second. Find the numbers.

a + b + c = 105

c = 10b - 11

2a = 3b + 7
