Add 9w to both sides
Subtract 23 from both sides
---
9w = -18
Divide both sides by 9 to get:
w = -2
===================================
#2: (3/2)a-8 = 7
Add 8 to both sides:
(3/2)a = 15
---
Multiply both sides by (2/3) to get:
(2/3)(3/2)a (2/3)15
a = 10
========================================
#3: 7=c/-5+3
7 = (c/-5) + 3
Subtract 3 from both sides
4 = (c/-5)
Multiply both sides by -5 to get:
c = -5*4
c = -20
========================================
#4: 6+-12+h/-7
Not an equation.
