Question

the poetry club has 129 members. There are 15 more girls than boys in the poetry club. How many boys are in the poetry club?

Answer 1

The answer is 57 boys.

Explanation:

So we need to craft an equation. We know the members, that will be our output. And we also know that there are 15 more girls. so, we will create the equation below.

A+A+15=129

A represents the boys.

So you need to merge the A's because they are the same varible.

2A+15=129

Subtract 15 from both sides.

2A=114

Now you need to divide both sides by 2

A=57 boys

And yeah, that's how you solve using equations. Simple and fairly easy for these types of problems. Hope this helps!

Answer 2

The correct answer is 72.
