Basically, all you have to do is substitue the terms given at the top.
x = -3 
y = 6
z = -4 
<em>The first one will be set up like this:</em>
(-3) + 6 + (-1) = 2
<em>The second one will be set up like this: </em>
-15 + (- -3) + 6 = -6
<em>The third one will be set up like this:</em>
3(-3) - 2(6) + (-4) = -25
<em>The fourth one will be set up like this:</em>
2(-4) - 3 (6) + 4(-3) = -38
<em>The fifth one will be set up like this: </em>
3 ( -3) + 2 (6) + (-4) = -1
<em>The sixth will be set up like this: </em>
(-3)(-4)
---------- = -1
-2 (6) 
<em>The seventh will be set up like this:</em>
2 (6) (-4) - 3 (-3) = -39

Instead of X put 5 and instead of y put 2
5+6(2) 
5+12= 17
