Homework Help: algebra

Posted by Anneliese on Wednesday, February 25, 2009 at 5:46pm.

In the magic square shown (I'll type it out), the sum of the numbers in each row, column, and diagonal are the same. Five of these numbers are represented by v,w,x,y, and z. Find y + z.

Here's what the magic square looked like. I'll type semi-colons to separate each "square."

v; 24; w
18; x; y
25; z; 21

I don't know how to solve this at all. Considering that all of the other problems on this worksheet had to do with systems of 3 equations with 3 variables, I'm assuming I'll have to make a system of equations. How would I find this information in the magic square?
