You can put this solution on YOUR website!
Let k = Kyle's age now.
Then the age of Kyle's aunt NOW is 3k.
The age of Kyle 5 years age is k-5.
The age of Kyle's aunt 5 years ago is 3k-5.
You need to use the following equation to set up an equation:
"Five years ago, his aunt was four times as old as Kyle"
I.e., The age of Kyle's aunt 5 years ago = 4*(The age of Kyle 5 years age)
So
3k-5=4(k-5)
