Solve the following systems of linear in equations:

3x – x > x + > 3

3x – x > x + and x + > 3

When,

3x – x > x +

2x > x +

Subtracting x from both the sides in above equation

2x – x > x + - x

x >

Multiplying both the sides by 3 in the above equation

3x > 3

3x > 4 – x

Adding x on both the sides in above equation

3x + x > 4 -x + x

4x > 4

Dividing both the sides by 4 in above equation

x > 1

Now when,

x + > 3

Multiplying both the sides by 3 in above equation

3x + 3 > 3(3)

3x + 4 – x > 9

2x + 4 > 9

Subtracting 4 from both the sides in above equation

2x + 4 – 4 > 9 – 4

2x > 5

Dividing both the sides by 2 in above equation
