Question

What is the solution set of the following equation?

Answer 1

Answer:

Option A) $\phi$ is the solution set for given equation.            

Step-by-step explanation:

We are given the following equation in the question:

$-8x + x + 15 = -7x + 12$

Solving the given equation, we have:

$-8x + x + 15 = -7x + 12\\-7x + 15 = -7x + 12\\-7x + 7x + 15 = -7x + 7x + 12\\15 = 12\\\text{which is never possible}$

Hence the given equation has no solution.

Thus, the solution set can be represented by a null set which can be represented as $\phi$

Option A) $\phi$ is the solution set for given equation.

Answer 2
