Question

What are the solutions to the equation ​

Answer 1

Explanation:

Dividing both sides of this equation by -5 results in y² = -21.

We can solve for y, but the two results will be imaginary (due to that - sign).

In this case, the solutions are {-i√21, i√21}.

If imaginary solutions are not acceptable to you, respond with "no solutions" or "no real solutions."
