Question

How do you write `x-5=0` in standard form?

Answer 1

`x=5` is (generally) considered the "standard form" for this equation.

Explanation:

In general the standard form for a linear equation is
`color(white)("XXXX")` `Ax+By = C`
`color(white)("XXXX")` `color(white)("XXXX")`with `A, B, C epsilon ZZ and A>=0`

In this case `A=1`, `B=0`, and `C=5`
So we could claim that the standard form was;
`color(white)("XXXX")` `1*x + 0*y = 5`
but this seems a bit pedantic.

`color(white)("XXXX")`On the other hand:
`color(white)("XXXX")` `color(white)("XXXX")`using the word "pedantic" is probably pedantic.
