Question 305989: solve the linear inequality
3z-1 > (or equal to) 3+5z
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
3z-1 >= 3+5z
3Z-5Z>=3+1
-2Z>=4
Z<=4/-2 { NOTE THE SIGN CHANGE WHEN DIVIDING BY A NEGATIVE VALUE]
Z<=-2 ANS.
PROOF
LET X=-2.1
3*-2.1-1>=3+5*-2.1
-6.3-1>=3-10.5
-7.3>=-7.5
