3+2(1-x) > 6 or 2x+14
3+2-2x>6
5-2x>6
-2x>1
x<-1/2
or
2x+14<=8
2x<=-6
x<=-3
Assuming this is one question
x<-1/2 or x<=-3
the second part is redudant cause every x<=-3 is also x<-1/2
answer: x<-1/2

3+2(1-x) > 6
3 + 2 - 2x > 6
5 - 2x > 6
-2x >1
x < -1/2 (switch sign when divide by neg)
2x+14
2x <= -6
x <= -3

1. 3 + 2 - 2x > 6
...-2x > 1
...x < -1/2
2. 2x <= -6
...x <= -3

3 + 2(1-x) > 6
3 + 2 -2x > 6
5 - 2x >6
-2x > 1 ---------------------------- eq 1
2x + 14 <= 8
x + 7 <= 4 (divided by 2)
x <= -3 ---------------------------- eq 2
Solution is x > -1/2 and x <= -3
i.e -1/2< x <= -3
X can have any value between -0.5 to -3

3+2-2x>6
-2x>6-5
-2x>1
x>-1/2
In my defens, x can not be either less then one number or less then another
value of x is any where between -1/2 to -3 not including -1/2
2x+14<=8
2x<=-6
x<=-3

Lmao. i will help you be attentive to those my females do this the lads do. my females no longer without postpone locate each dirt puddle out of your place to the church, even once you're using there. Their rooms are generally messy they're going to %. up a stick and swap it right into a gun ( and that i hate it) the girls gets / locate makeup and intensely almost instinctively start up portray the partitions. and flooring with it my females will burp and that they're going to persist with it with a dozen pretend belches. And the main one that is fairly like my oldest daughter is that in case you swap off the VCR while they have watched "Teenage Mutant Ninja Turtles" movie three times in a row she would be waiting to stand up beat the **** out of you lol. i think of my females are boys lol

Kids need to stop coming on here in hopes of people doing their homework for them, read the textbook and learn it yourself.
