There are 33 students in an Algebra I class. There are 7 fewer girls than boys. How many girls are in the class?

Let b be the number of boys and g be the number of girls. We are given 2 equations:

1. g = b - 7
2. b + g = 33

Substitute (1) into (2):
b + (b - 7) = 33

Combine like terms:
2b - 7 = 33

Typing this equation into our search engine, we get b = 20.

Since the problem asks for how many girls (g) we have, we substitute b = 20 into Equation (1):
g = 20 - 7
g = 13
