Question

The product of two numbers is 340 If one number -17, how do you find the other number?

Answer 1

The other number is `color(green)(""(-20))`

Explanation:

Given that one number is `(-17)`, let the other number be represented by the variable `x`.

We are told that `340` is the product of `(-17)` and `x`.

That is
`color(white)("XXX")(-17) xx x= 340`

If we divide both sides by `(-17)`
`color(white)("XXX") (cancel(""(-17))xx x)/cancel(""(-17)) = (cancel(340)^(-20))/cancel(""(-17)))`

`color(white)("XXX")x =-20`

Answer 2

The other number is `-20`.

Explanation:

Let `-17` equal the known factor and `x` equal the unknown factor.

`-17*x=340`

Simplify.

`-17x=340`

Divide both sides by `-17`.

`x=-20`
