Question

l -6 +12 l Less than equal to 18

and

l -6 + 12 l greater than equal to -18

Answer 1

|-6+12| = |6| = 6 < 18, also 6<18

|-6+12) = |6| = 6 > -18, also 6> -18

is it possible you left out a variable?

usually these problems would look more like |-6+12x| < 18. then you could solve for x

-1 < x < 2
