Question

How do you find the product of `3z-6x`?

Answer 1

An answer, assuming `3z xx 6x` was meant

Explanation:

I'll answer this assuming the question is meant to be `3z xx 6x`

The operation holding the 3 and the `z` together is multiplication, as is `6 xx x`, and so we can rewrite the question as:

`3xxzxx6xx x`

I can reorder this and not change the value of the multiplication:

`3xx6xx x xx z`

And I can group things together:

`(3xx6)xx x xx z`

`3xx6=18`, and so:

`18xx x xx z`

At this point I can't do anything else. Both `x` and `z` are unknown values and so we simply leave them alone. Since we can write multiplication simply by having the variables sit next to other variables or constants, I can write the expression as:

`18xz`
