Question

How many solutions does this equation have?

8z − 5 = 8z

Answer 1

Zero

Explanation:

Solve the equation by subtracting 8z from both sides:

8z − 5 = 8z

-5 = 0

-5
0

This is a false statement, because -5 is not equal to zero.

This means that there are no solutions to the equation.

So, the equation has zero solutions

Answer 2

Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.
