Answer:
1. -21
2. 0
3.
Step-by-step explanation:
1. 18 =
multiply both sides by the reciprocal of -6/7.
18 =
-21 = h
-------------------
2.
find the LCM of both fractions.
LCM = 8
multiply both fractions by the LCM
-6x = 21x
subtract 21x from both sides
-6x-21x = 21x-21x
-27x = 0
isolate x
-27x/-27 = 0
x = 0
-------------------
3.
multiply both sides by the reciprocal of -1/2.
z =
hope this helps :)

Remember that an absolute value is the measure of something's distance from 0 on the number line. A key piece of that idea is that distances cannot be negative.
So, any absolute value set equal to or less than 0 or any negative number cannot have any solution.
Working out way up from the bottom...
That bottom one, is clearly an issue, since you have an absolute value set less than -2.
To decide on the others, you need to get the absolute value by itself.
On the third inequality, you need to divide by -2 to get the abs val by itself. When you do that, you'll end up with |3x-5| ≤ -3/2. That's a problem, so that won't have any solution.
On the second one, you'd start by subtracting 17 from both sides and you'd get |3x-6| > -2. That'll always be true, since an absolute value is always 0 or positive.
And you have the same thing with the first inequality too, that it's already set > a negative, so it's always true.
So, just the last two will not have solutions.
Consider factors of 42, then if the factors can be added or subtracted.
42 = 42 * 1
42 = 21 * 2
42 = 14 * 3
42 = 7 * 6
Since none of these can be added or subtracted to equal 15, no intergers satisfy these criteria.
