b.
To find: The number of solutions the equation has ‘one’ or ‘more than one’ or ‘none’.
b.
Answer to Problem 42WE
The equation has none solution.
Explanation of Solution
Given information:
Calculation:
Let’s solve the equation for ‘ x’ .
Subtract both sides x .
It gives equation as ,
The equation is false, so there is no solution to the equation.
Conclusion: So the equation has solution as none.
