Mathematics

(-∞,∞)

Step-by-step explanation:

PART A:

given 5+x-12=x-7

$5+x-12=x-7\\x-7=x-7\\x=x\\$

This is true for all values of x.

So,x∈-∞,+∞

PART B:

When x=4 ,left hand side= 5+4-12=-3

right hand side= 4-7=-3

so,left hand side =right hand side

When x=0 ,left hand side= 5+0-12=-7

right hand side= 0-7=-7

so,left hand side =right hand side

When x=5 ,left hand side= 5+5-12=-2

right hand side= 5-7=-2

so,left hand side =right hand side
