Question

Negative nine times a number equals -117

Answer 1

Let's have X represent the number we're looking for.
Times means that we are multiplying, so let's make an equation.
-9x=-117
We know by looking at this equation that the number is positive since the number is multiplied by a negative and the answer is negative.
Let's get x by itself by dividing both sides by -9.
-117÷-9=13=x

So, the number is 13.

Answer 2

-9(x) = -117

Solve for "a number" (x). Isolate it. Note the equal sign. What you do to one side, you do to the other. Divide -9 from both sides.

-9x/-9 = -117/-9

x = -117/-9

x = 13

13 is your answer
