1. -21
2. 0
3.
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 =
