a. x < 5
b. x > 5
c. x < -5
d. x > -5

Answer 1

Add x + 5 to both sides.

Answer 2

I did, but I still don't know the answer. Like whether the sign is suppose to be flipped or not?

Answer 3

you have a choice

Answer 4

I think it's A or B ?

Answer 5

it is b

Answer 6

If you add or subtract things from both sides of an inequality you never change the direction. The only time you change direction is if you multiply by a negative.

Answer 7

Or divide.

Answer 8

you can solve either by flipping the inequality or by making sure by addition that the variable has a positive coefficient

Answer 9

So there are two ways you can solve it. Either add x+5 to both sides and keep the direction the same, or multiply both sides by -1 and change the direction of the inequality.
