Answer:
Jack is 88, Priscilla is 75.
Step-by-step explanation:
Let J represent Jack's age and let P represent Priscilla's age.
Their age totaled 163, so:
And we know that Jack was 13 years older than Priscilla. In other words:
Solve for J and P. To do so, substitute the second equation into the first:
Combine like terms:
Subtract 13 from both sides:
Divide 2 from both sides:
So, Priscilla is 75 years old right now.
Jack is 13 years older meaning that Jack is 88 years right now.
And we're done!
