Answer: Charlotte and Isaac
Explanation:
1.) 24=19+n- Rewrite the equation, so you can actually see what you're doing.
2.) 24=19+n- The second step is to subtract 19 from both sides of the equation- Answer: 5=n
3.) Yay! You figured it out!
4.) Answer: 5=n
5.) Overall, Charlotte and Isaac are both correct, because if you plug the number 5 back into the equation, you will get 24.
