The volleyball club has 41 members. There are 3 more boys than girls. How many girls are there? How many boys are there?

Question

show all work and determine if elimination or substitution

Answer 1

Let x be the number of girls

and x + 3 be the number of boys.

x + x + 3 = 41

2x + 3 = 41

2x = 38

x = 19

So there are 19 girls.

There are x + 3 is boys

so 19 + 3 = 22

No of boys is 22.

Answer 2

First step is to define the variables.

x= boys, y = girls

Then, it is necessary to make 2 or 3 equations depending on the question. Because there are 3 more boys than girls, if we add 3 to the girls then the values will be equal.

y+3 = x

y+x = 41

I will use the substitution method in this case because it is already set up.

y+ (y+3) =41

2y+3 = 41

2y = 38

y = 19

Therefore, there are 19 girls and (41-19) 22 boys.
