Question 684595: If you add the sqaure of tom's age to the age of carol, the sum is 62; but if you add the square of Carol's age to the age of Tom, the result is 176. Determine the age of tom and carol.
I tried
Tom's age Sq.Rt of T + C = 62
Carol's age Sq.Rt of C + T = 176
how do I solve this?

You can put this solution on YOUR website! If you add the square of tom's age to the age of carol, the sum is 62;
but if you add the square of Carol's age to the age of Tom, the result is 176.
Determine the age of tom and carol.
:
Here is a situation where graphing would be the easiest way to solve this
Let x = Carols age
Let y = Tom's age
:
Write a slope intercept equation for each
x^2 + y = 176
y = 176 - x^3
and
x + y^2 = 62
y =
:
Plot these two equation, find the intersect
we expect to be dealing with integers here, therefore we can see
x = 13, y = 7
:
Tom is 7, Carol is 13
