Question

Product of two numbers is -216. If one of the number is 12, find the other number

Answer 1

$\huge\boxed{-18}$

We know that $xy=-216$, where $x$ and $y$ are the two numbers.

We know that one of the numbers, $x$, is equal to $12$.

$12y=-216$

We need to find the value of $y$. To do so, we must isolate it. In this case, we can isolate $y$ by dividing both sides of the equation by $12$.

$y=\boxed{-18}$

Now, let's check our answer. If we multiply the two factors together, we should get a product of $-216$.

$12*(-18)=-216$

$-216=-216\ \ \huge\checkmark$
