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 $\frac{-81x+27}{3}$. 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 $\frac{-81x+27}{21}$. 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
