Let Cody be x years old now. and y be Evan's age now.

x = 2y

x -7 + y - 7 = 10

x + y =  24 
Substitute for  x = 2y:-

2y + y = 24

y = 8   

and therefore
 x = 2*8 = 16

Answer is Cody is now  16 and Evan is 8

Answer:

Equation: 15 - f = n

Answer: n = 9

Step-by-step explanation:

The question is asking to write the equation. The equation would be

"15 - f = n" where f  shirts folded

n = shirts remaining to fold

Then the question has gave us the value of f and has told us to solve it. Below is the solution.

15 - 6 = n

=> n = 9

Therefore, there is 9 shirts remaining after 6 of them are folded.

What did we solve?

We wrote our equation and solved what was required in the question.

I hoped this helped.

If possible... May I have brainliest :)
