Solve the following systems of linear in equations:
–12 < 4 – ≤ 2
-12 < 4 – and 4 –
≤ 2
When,
-12 < 4 –
4 – > -12
Subtracting 4 from both the sides in above equation
4 – -4 > 12 – 4
– > -16
> -16
Multiplying both the sides by 5 in the above equation
> -16(5)
3x > -80
Dividing both the sides by 3 in above equation
>
Therefore,
x >
Now when,
4 – ≤ 2
Subtracting both the sides by 4 in the above equation
4 – – 4 ≤ 2 – 4
– ≤ - 2
≤ -2
Multiplying both the sides by 5 in the above equation
3x ≤ -10
Dividing both the sides by 3 in the above equation
≤
Therefore,
Therefore:
