Eight multiplied by a number is 86

1 answer:

4 0

To find this, we would set up an equation. it would look like this:
8x=86 [ x is the unknown number ]
to have x by itself, we divide by 8 on both sides and end up with:
x=86/8 , which can be simplified to 43/2.
the number is 43/2 (:
hope this helped! xx
