Answer:
24 + 2n = 40
Step-by-step explanation:
let the number be n , then two times the number is 2n
This is then added to 24 and equal to 40
24 + 2n = 40 ← in equation form
24 + 2(n) = 40
You could use any letter just n is preferable since something is absent and that thing is a number - so it starts with N. Good luck!
