Question

2 number:?+?=45

Answer 1

`x+y=45`
[Read explanation for answer]

Explanation:

You need two numbers that add to `45`.
What we need to do is equal out the equation so we have `45` on both sides.
Therefore, the addition of our two numbers `x` and `y` must equal `45`
or
`x+y=45`

We can solve this equation for `y` and get:
`y=45-x`

Now give `x` any value and substitute it into our equation to get the value of `y`.
Here is an example:

[Let x equal 20]

`y=45-x`

`y=45-20`

`y=25`

So our values are `x=20` and `y= 25`
We can check our answer by substituting it into our original equation.

`x+y=45`
`20+25=45`
`45=45`

You can give x any value and find two numbers that add to 45 this way.
