Thread: How To Solve This Inequality?

6x+4 <= x-6 < 4x + 10

My work:
6x+4 <= x-6 < 4x + 10
6x+4+6 <= x < 4x+10+6
6x+10 <= x < 4x+16

Not really sure how to finish this...

It's much easier if you break it into two separate inequations and then bring the solutions together at the end if necessary:




Can you finish it off now?

solve it like this

6x+4<=x-6

5x <= -10

x <= -2 this the first interval

x-6 < 4x+10

3x > -16

x > -16/3 now find the intersection of the two intervals (-infinity , -2] and (-16/3 , infinity)
