Given the equation 5+x-12=x-7:
part a. solve the equation 5+x-12=x-7. in your final answer, be sure to state the solution and include all of your work.

part b. use the values x=4,0,5 to verify your solution to the equation 5+x-12=x-7. in your final answer, include all of your calculations.

Step-by-step explanation:

PART A:

given

This is true for all values of x.

So,x∈-∞,+∞

PART B:

When ,left hand side=

right hand side=

so,left hand side =right hand side

When ,left hand side=

right hand side=

so,left hand side =right hand side

When ,left hand side=

right hand side=

so,left hand side =right hand side
