Answer 4

ok hold on

Answer 5

is that trial and error by chance?

Answer 6

Hey winston

Answer 7

I believe so. I already know that 3 won't work. So I just need to know if the direction of the sign needs to change.

Answer 8

if its trial and error, then youve approached the correct answer :)

there is a more mathical approach to it if you know how to implement the properties of algebra

Answer 9

Thanks. I just wanted to make sure. Is it because I didn't need to divide or multiply, therefore I don't need to change the sign?

Answer 10

.6x +12 +x > 2x +9 -.5x

1.6x +12 > 1.5x +9

.1x +12 > 9

.1x > -3

x > -3/.1

x > -30
