B) 3x - 4 = - 83x = - 8 + 4
3x = - 4
x = - 4/3
c) - 4 - 2 = x + 4
- 6 = x + 4
x = - 6 - 4
x = - 10
d) n + ( n + 1 ) + ( n + 2 ) = 27
3n + 3 = 27
3n = 27 - 3
3n = 24
n = 8
e) 2y + 5 = y - 1
2y - y = - 1 - 5
y = - 6
f) 2 ( 2a - 1 ) = 2a + 6
4a - 2 = 2a + 6
4a - 2a = 6 + 2
2a = 8
a = 4
g) ⅔x + 9 = - 3
⅔x = - 3 - 9
⅔x = - 12
x = - 12 ÷ ⅔
x = - 12 × 3/2
x = - 18
