### Simple Equation in one variable

The linear equations in one variable is an equation which is expressed in the form of **ax+b = 0**, where a and b are two integers, and x is a variable and has only one solution

**Que-1: Solve : (i) x-4 = 8 (ii) x+7 = 2 (iii) x-6 = -3 (iv) y+2 = -6 (v) x+3 = -1 (vi) z-5 = -8**

**Sol: **(i) x – 4 = 8

x = 8+4 = 12

(ii) x + 7 = 2

x = 2-7 = -5

(iii) x – 6 = -3

x = -3+6 = 3

(iv) y + 2 = -6

y = -2-6 = -8

(v) x + 3 = -1

x = -1-3 = -4

(vi) z – 5 = -8

z = -8+5 = -3

**Que-2: Solve : (i) x/3 = 6 (ii) y/2 = -4 (iii) 2x/4 = 3**

**Sol: **(i) x/3 = 6

x = 6×3 = 18

(ii) y/2 = -4

y = -4×2 = -8

(iii) 2x/4 = 3

x = 3×(4/2) = 6.

**Que-3: Solve : (i) 2x = 10 (ii) 3y = -12 (iii) 2x-3 = 7 (iv) 3x-5 = 4 (v) 4x-1 = 7 (vi) 5z-3 = 2**

**Sol: **(i) 2x = 10

x = 10/2 = 5

(ii) 3y = -12

y = -12/3 = -4

(iii) 2x – 3 = 7

2x = 7+3

x = 10/2 = 5

(iv) 3x – 4 = 5

3x = 5+4

x = 9/3 = 3

(v) 4x – 1 = 7

4x = 7+1

x = 8/4 = 2

(vi) 5z – 3 = 2

5z = 2+3

z = 5/5 = 1

**Que-4: Solve : (i) 2x-3 = -5 (ii) 4y+5 = -3 (iii) 6z-8 = 1**

**Sol: **2x – 3 = -5

2x = -5+3

x = -2/2 = -1

(ii) 4y + 5 = -3

4y = -3-5

y = -8/4 = -2

(iii) 6z – 8 = 1

6z = 1+8

z = 9/6 = 3/2.
