what is Triple the difference of 20 and a number

Question

I need to know the answer

Answer 1

The "difference of 20 and a number" (x) would be written as: 20 - x

Then, "triple" (or 3 times) this difference would be written as: 3(20 - x)

Using the distributive property, this can also be written as: 60 - 3x
