Is x > 1?
1. 2x+5 > 2-x
2. |x-12| = 12-3x
from 1
When we solve the inequulity
we will get x > -1
which will answer the question as No, when x =0
which will answer the question as Yes, when x =2
from 2
x-12 = 12-3x or -x+12 = 12-3x
x = 6 or x = 0
Now we did get 2 values here,
but will they both satisfy the modulus, lets see
At x = 6
|6-12| = 12-18
6 ! = 6, Not a valid value
At x = 0
12 = 12, True
So only one value comes out,which will answer the question as No
B
