Answer:
c. ax+b=ax+b
Step-by-step explanation:
To know what equation has infinite solutions, you first try to simplify the equations:
a.
In this case you have that a must be different of b, but there is no restriction to the value of c, then c can be equal to a or b.
b.
Here you obtain that b = c. But the statement of the question says that a, b and c are three different numbers.
c.
In this case you have that whichever values of a, b and are available solutions of the equation. Furthermore, when you obtain 0=0, there are infinite solutions to the equation.
Then, the answer is:
c. ax+b=ax+b
