Is 1x the same answer as x by itself

Question

Is 1x the same as x by itself

8x-7x+4

 

1x+4 is our answer, but the book says x+4

Answer 1

Hi Denise,

 

Yes, 1x is the same as x.

 

Technically, the "1" in front of the "x" is called an "implied 1" and, so it's simply written as x.

 

Here's, an example that should make this clear:

    Say x = 4

    Then (1)(x) = (1)(4) = 4 = x

 

Just simply means that any value multiplied by 1 is always equal to itself.

 

Trust the above explanation helps.

 

God bless, Jordan.
