Question

2x + 1 < 1 OR x + 5 > 8

Answer 1

2x + 1 < 1 OR x + 5 > 8


2x < 1 - 1 OR x > 8 - 5


2x < 0 OR x > 3


x < 0/2 OR x > 3


x < 0 OR x > 3

Answer 2

how did you do that? you switched the signs?

Answer 3

which step?

Answer 4

2nd

Answer 5

the signs are the same as the first step

Answer 6

no?

Answer 7

I'm dealing with each inequality individually

Answer 8

I solved 2x + 1 < 1 to get x < 0

Answer 9

separately, I solved x + 5 > 8 to get x > 3

Answer 10

but if you do it to one side dont you do it to the others?

Answer 11

that's what I'm doing when I did 2x < 1-1, I subtracted 1 from both sides (first inequality only)

Answer 12

oh.

Answer 13

going from 2x + 1 < 1 to 2x < 1-1, the sign does not change

Answer 14

thanks
