Question

Which of the following equations have infinitely many solutions? Choose all answers that apply:

Answer 1

Answer:

B.

C.

D.

Explanation:

If you plug in any value to both sides of the 3 equations, they'll always match. Take C. for example.

On the left side, we have: -19 times 1 plus 91=72

On the right side, we have: -19 times 1 plus 91=72

As you can see, the result is the same. This works with any x-value, not just 1.
