Question 1137112
let x equal her age today.


in 16 years, she will be 5 times older than she was 4 years ago.


the equation for that would be x + 16 = 5 * (x - 4) + (x - 4).


simplify that equation to get x + 16 = 6 * (x - 4).


that means she will be 6 times as old as she was 4 years ago.


simplify that equation to get x + 16 = 6 * x - 24.


add 24 to both sides of this equation and subtract x from both sides of this equation to get 40 = 5 * x.


solve for x to get x = 40 / 5 = 8.


she is 8 years old today.


4 years ago she was 4 years old.


16 years from now, she will be 24 years old.


24 years old / 4 = 6.


that means that she will be 6 times 4 years old in 16 years.


if she will be 6 times 4 years old in 16 years, subtract 4 from that and you will get she is 20 years older than 4 years old which means she is 5 times older than she was 4 years ago.


24 / 4 = 6 times as old.


(24 - 4) / 4 = 20 / 4 = 5 times older.


if this is not the answer you are looking for, then send me an email and i'll revise the answer from her being 5 times older to her being 5 times as old.


there is a difference between the two statements and it's a very important difference.
