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

1 Answer

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#
