Question

THREE expressions equivalent to –81x+27.

Answer 1

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us
`(-81x+27)/(3)`. If we simplify this, we get
`-27x+9`.

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us
`(-81x+27)/(21)`. If we simplify this, we get
`-3x+1`.

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us
`1(-81x+27)+0`.

Have a terrificly amazing day! :D
