Answer:
A. Jane is 13 and Harvey is 39
Explanation:
Let's say Harvey's age is H and Jane's age is J
Given:
H = 3J
H + J = 52
Use substitution to find Jane age:
H + J = 52
(3J) + J = 52
4J = 52
J = 13
Plug J-value in any equation to find H-value:
H + J = 52
H + 13 = 52
H = 39
Therefore, Jane is 13 and Harvey is 39. Answer A would be the correct answer.
