Chapter 9: Q. 9.148 (page 1094)

For the equation -x+2=x:

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

Part (b): Isx=1a 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+2=x

02

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

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

--2+2=-22+2=-24=-22=-2

It is not possible.

Hence, it is not a solution.

03

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

Assume x=1and substitute it in the given equation,

-1+2=11=11=1

It is possible.

Hence, it is a solution.
