(a) 2 (x + 4) = 12
(6) 3 (n – 5) = 21
(c) 3 (n – 5) = – 21
(d) -4 (2 + x) = 8
(e) 4 (2 – x) = 8

Question 3.
Solve the /bilowing equations :
(a) 4 = 5 (p – 2)
(b) -4 = 5 (p – 2)
(c) 16 = 4 + 3 (t + 2)
(d) 4 + 5 (p – 1) = 34
(e) 0 = 16 + 4 (m – 6).
Solution:
Question 4.
(a) Construct 3 equations starting with x = 2
(b) Construct 3 equations starting with x = – 2.
Solution:
(a)
1. Start with x = 2
Multiply both sides by 3, 3x = 6
Subtract 2 from both sides, 3x – 2 = 4 …(1)
2. Start with x = 2
Multiply both sides by 4, 4 x = 8
Add 5 to both sides, 4x + 5 = 13 …(2)
3. Start with x = 2 Multiply both sides by 5 5x = 10
Subtract 1 from both sides, 5x – 1 = 9 …(3)
(b)
1. Start with x = – 2
Multiply both sides by 3, 3x = – 6
Subtract 2 from both sides, 3x – 2 = – 8 …(1)
2. Start with x = – 2
Multiply both sides by 5, 5x = – 10
Subtract 1 from both sides, 5x – 1 = – 11 …(2)
3. Start with x = – 2
Multiply both sides by 4, 4x = – 8
Add 5 to both sides 4x + 5 = – 3 …(3)
