Question 99754: This should be easy, but no combination seems to come out "correct" according to my submission. It's supposed to be solved and put in interval format.
7x+12<=6
So I tried
subtract 12 from bothsides 7x<=-6
then divide by 7 for x<=-6/7
So interval format should be (inf, -6/7]
But I'm wrong. Please help! Thanks!
