Question

Linear equations 10=1+n

Answer 1

Hey!

First, let's solve n

`10 = 1 + n`

Switch the equation around:

`1 + n = 10`

Switch it again:

`10 - 1 = n`

The sign changes when switched to the other side. At first, it was (+), and now it's (-).

`10 - 1 = 9`

`\framebox{n = 9}`

Here is a graph:
