The sum of two numbers is twenty-four. The second number is equal to twice the first number. Call the first number m and the second number n.

Step-by-step explanation:

Hello, please consider the following.

m and n are the two numbers.

m + n = 24, right?

n = 2 m

We replace n in the first equation, it comes

m + 2m =24

3m = 24 = 3*8

So, m = 8 and n = 16

Thank you

first number = 8

second number = 16

Step-by-step explanation:

m + n = 24

n = 2m

then:

m + 2m = 24

3m = 24

m = 24/3

m = 8

n = 2m

n = 2*8

n = 16
