The number of x's is the same on both sides of the equation and the constant is also the same a = b, c₁ = c2

A. No solution

B. Two solutions.

C. Three solutions.

The given equation is a = b, and the given condition is c₁ = c₂.

Since a = b, any value of a will also be a value of b.

Since c₁ = c₂, any value of c₁ will also be a value of c₂.

Therefore, the equation has infinitely many solutions.

Therefore, the correct answer is:

D. Infinitely many solutions.

Based on the given information, "The number of x's is the same on both sides of the equation and the constant is also the same, a=b, c₁=c₂," we can conclude that there is a unique solution for the equation.

Therefore, the correct answer is A. No solution.
