if x(y)=24 what is x+z=9 and y+z=7

Easy...

x*y = 24

x + z = 9

y + z = 7

The factors of 24 are 1,2,3,4,6,8,12,24.

When testing these out we should start with the middle two first: 4,6.

We'll let x = 6 and y = 4.

Then we have the equation x + z = 9, simplified to

6 + z = 9

so z = 3.

Now testing for the third equation, y + z = 7.

We have y = 4, and z = 3 sooooo

x=6

y=4

z=3

If I got anything wrong please say it.
