Question #3098c

Answer 1

181 and 169

Explanation:

This is a simultaneous equation problem.

Let `x` be one of the numbers, and `y` be the other.
`x+y=350`
`x-y=12`

Let's solve by eliminating b since one of the equation is `+y` and the other is `-y`.

Add the two equations

`2x=362`

Divide both sides of the equation by `2`

`x=181`

Substitute `x=181` into either of the equations

If you chose the first one,

`181+y=350`

Take away 181.

`y=169`

If you chose the second one,

`181-y=12`

Add `y` to both sides

`181=y+12`

Take away 12 from both sides

`y=169`
