Solve each of the following in equations and represent the solution set on the number line.
, where x ϵ R.
Given:
Now, multiplying by 12 on both the sides in the above equation,
-x + 4 > 12
Now, subtracting 4 from both the sides in above equation
-x + 4 – 4 > 12 – 4
-x > 8
Multiplying by -1 on both the sides of the above equation
x < - 8
