Question

Solve |2x+1|-3 >6

Answer 1

First add 3 to both sides.
2x + 1 > 9
Subtract 1.
2x > 8
Divide.
x > 4

Answer 2

That the first one the second one I got -5 is it right?

Answer 3

Also, you're supposed to have a set of answers for these kind of problems. So x > 4 is only gonna be half of your answer. You have to flip the > sign to be < and change the sign of the 6 to -6.
|2x + 1| - 3 < -6
Again, add 3.
2x + 1 < -3
Subtract 1.
2x < -2
Dividdeeeee.
x < -1.

Answer 4

So it's x > 4 AND x < -1.

Answer 5

Why equal 6.

Answer 6

Isn't it 2x+1<-9

Answer 7

No because to find the other part of the set, you have to swap the greater than/less than sign and flip the sign of the number with it. So since the first problem is > 6, the second one would be < -6.

Answer 8

Oh ok thank you very much :)
