Answer:
Option A) [tex]\phi[/tex] is the solution set for given equation.
Step-by-step explanation:
We are given the following equation in the question:
[tex]-8x + x + 15 = -7x + 12[/tex]
Solving the given equation, we have:
[tex]-8x + x + 15 = -7x + 12\\-7x + 15 = -7x + 12\\-7x + 7x + 15 = -7x + 7x + 12\\15 = 12\\\text{which is never possible}[/tex]
Hence the given equation has no solution.
Thus, the solution set can be represented by a null set which can be represented as [tex]\phi[/tex]
Option A) [tex]\phi[/tex] is the solution set for given equation.
