x/2 = 20
20 * 2 = 40
40/2 = 20
20 = 20
Is this correct?
no, here is the best way to solve it (imo) because i didn't see it on the first or last page
x/2 = 20
multiply both sides of the equation by 2 to get rid of the division sign. Note that doing the same thing to both sides will not affect the answer in a problem like this.
Then you have:
(x/2)*2 = 20*2
multiply the stuff out
you end up with
x = 40
Are we still arguing about simple arithmetic?
Of course, it's not like we have anything better to do
