Question

How do you solve this?

Answer 1

There are 8 boys in the chorus and 16 girls in the chorus

The graph in the attached figure

Explanation:

Let

x----> the number of boys

y----> the number of girls

we know that

`y=2x` -----> equation A

`x=y-8` ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (8,16)

see the attached figure

therefore

There are 8 boys in the chorus

There are 16 girls in the chorus
