49 students went on a trip .There are 5 more girls than boys.How many boys are there?

Answer 1

b = numer of boys

g = number of girls

There are 5 more girls than boys.

g = b + 5

b + g = 49

b + b + 5 = 49

2 b + 5 = 49 Suptract 5 to both sides

2 b + 5 - 5 = 49 - 5

2 b = 44 Divide both sides by 2

2 b / 2 = 44 / 2

b = 22
