2x-%284y-3%29%2B5xz when x=-3,+y=2, and Z=-1
substitute x=-3,+y=2, and Z=-1 in 2x-%284y-3%29%2B5xz (be careful with negative signs
2%28-3%29-%284%2A2-3%29%2B5%28-3%29%2A%28-1%29 ...recall the rules:
-if you multiply positive and negative number,their product is negative number
-if you multiply negative and negative number,their product is positive number

-6-%288-3%29%2B5%2A3
-6-5%2B15
-11%2B15
