HOME ASSIGNMENT-2

1. Give first the step you will use to separate the variable and then solve the equation

(a) x – 1 = 0
(b) x + 6 = 2

2. Give first the step you will use to separate the variable and then solve the equation

(a) 3l = 42
(b) b/2 = 6

3. Give the steps you will use to separate the variable and then solve the equation

3n – 2 = 46

4. Solve the following equations

(a) 10p + 10 = 100
(b) 3p/4 = 6
(c) 3s + 12 = 0

.

Ans:

1. Give first the step you will use to separate the variable and then solve the equation

(a) x – 1 = 0---------x-1+1 =0+1

x= 1

(b) x + 6 = 2------------ x+6-6=2-6

x= -4

2) a)3l = 42 3l/3= 42/3 l= 14 b) Ans=12

3)3n – 2 = 46

3n-2+2= 46+2
