**Simple Equations**

** Question 1.****Solve the following equations :**

**Solution:**

**Question 2.****Solve the following equations :(a)** 2 (x + 4) = 12

**(b)**3 (n – 5) = 21

**(c)**3 (n – 5) = -21

**(d)**-4 (2 + x) = 8

**(e)**4 (2 – x) = 8

**Solution:**

**Question 3.****Solve the following 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) First equation :**

Start with x = 2

Multiply both sides by 3, 3x = 6

Add 2 to both sides, 3x + 2 = 8

**Second equation :**

Start with x = 2

Multiply both sides by -3, -3x, = -6

Add 8 to both sides, 8 – 3x = 2.

**Third equation :**

Start with x = 2

Divide both sides by 5, =

Subtract 2 from both sides,

**(b) First equation :**

Start with x = -2

Multiply both sides by 2, 2x = -4

Subtract 3 from both sides, 2x -3 = -7

**Second equation :**

Start with x = -2

Multiply both sides by – 5, – 5x = 10

Add 10 to both sides, 10 – 5x = 20

**Third equation :**

Start with x = -2

Divide both sides by 2, = -1

Add 3 to both sides, + 3 = 2
