Answer:
The answer is Infinitely many solution.
Step-by-step explanation:
Given the equation 5r + 10 − 5r = 10.
we have to find the number of solution.
5r + 10 − 5r = 10
⇒ when solving above equation we get
10=10
which implies the given equation has infinitely many solutions i.e any value of r satisfy the above equation.
Hence, last option is correct.
