How do you do this Algebra problem?
The sum of two numbers is 18. The sum of their squares is 164. What are the numbers?
~My brother is studying and I was trying to help, but I just can't remember how to do this kind.
Thanks

just make a system of equations:
x+y=18
X^2 + y^2= 164
slove for x or y on the first equation, then plug it in the second eqaution and solve.
the number is 10 and 8 since ten times ten is 100 and 8 times 8 is 64 add them and u get 164
