The equation has infinitely many solutions, if
The two sides are equal completely
Since ax + bx = ax + c
The two sides have the same terms of x, but a not equal C
Then this equation has no solution
A is not the answer
Since ax + b = ax + b
The two sides have the same term of x
The two sides have the same numerical terms
The two sides are equal completely
This equation has infinitely many solutions
B is the answe
