Homework Help: Math

In a game, the Bulls score a total of 103 points and made three times as many field goals (2 points each) as free throws (1 point each). They also made eleven 3 points. How many goals did they have?

103=3(2)+ 1 + 11(3)
would this equation be right?

No, that is not right.
Let the number of free throws be x.
There are 3x two-point field goals, and 11 from "downtown" (3 pointers).
103 = 11*3 + 2*(3x) + x
70 = 7x
x = 10 free throws
3x = 30 is the number of two-point "field goals"
