Question 65042
Hi! I need someone to please check my work on this. X=4, Y=-3, and Z=2 

GOOD WORK ON THIS ONE (1)!!!! YOU ARE RIGHT ON TARGET. 
1. Is 3x-2y+z>(or equal to)19?
3(4)-2(-3)+2>(or equal to)19
12(-6)+2>(or equal to)19
20>(or equal to)19
YES 


YOU NEED TO RECHECK THIS ONE (2). 
IN STEP 3, WHERE DID THE -3 COME FROM
THAT CAUSED THE SIGNS IN STEP 4 TO GET REVERSED
I THINK YOU MIGHT HAVE CONFUSED THIS WITH THE NEXT PROBLEM


2. Is 3(x+4y)<(or equal to)z
3(4+4(-3)<(or equal to)2
-3(4+-12)<2
-12+36<2
24<2
NO



YOU ARE RIGHT ON TARGET WITH IS ONE (3).  GOOD WORK!!

3. Is -3(x+4y)>z
-3(4+4*-3)>2
-3(4+-12)>2
-12+36>2
24>2
YES 


Hope this helps.  Happy holidays.----ptaylor
