For the equation x+6=x:

Part (a): Is x=-2a solution?

Part (b): Isx=3a solution?

Short Answer

Expert verified

Part (a): It is not a given solution.

Part (b): It is a given solution.

Step by step solution

01

Part (a) Step 1. Given information.

Consider the given equation,

x+6=x

02

Part (a) Step 2. Substitute x=2 in the given equation.

Assume x=2and substitute it in the given equation,

localid="1647877891548" -2+6=-24=-22=-2

It is not possible.

Hence, it is not a solution.

03

Part (b) Step 1. Substitute x=3 in the given equation.

Assume x=3and substitute it in the given equation,

localid="1647877928473" 3+6=39=33=3

It is possible.

Hence, it is a solution.
