Question

Write a multipulcation equation and a division equation which has a solution of -5​

Answer 1

We can start from $x=-5$ and multiply/divide both sides to generate an equation that has -5 as a solution. For example, if we multiply both sides by 3, we have

$3x=-15$

And this equation must be solved by dividing both sides by 3.

Vice versa, if we divide both sides by 2, we have

$\dfrac{x}{2}=-\dfrac{5}{2}$

And this equation must be solved by multiplying both sides by 2.
