You need to isolate the variable <em>h</em>.
1) Subtract both sides by 2.
-4h + 2 = 18
-4h + 2 - 2 = 18 - 2
-4h = 16
2) Divide both sides by -4 (the coefficient).
(-4h) / -4 = 16 / -4
h = -4

Step-by-step explanation:
Given
-
[ -
c + 6c + 1 ] - 3c
Distribute the square bracket by - 
=
c - 3c -
- 3c ← combine like terms
=
c - 6c - 
=
c -
c - 
= -
