Confusion with something real basic
So when we solve an equation for x.
Let's say
10+x = 20 or x*5=20 or 10-x=5 or something like that
In
If I do
10 = 20-x or x = 20-10
x= 20÷5 or 5 = 20÷ x
10=5+x or -x=5-10
All of them will give the same answer
But in division
10÷x=5
10= 5*x or x=5*10
Won't give the same answer
I know it sounds rather stupid but I wanna know why exactly.
Why is that only in division , we can only work with dividend.
While in other cases we can work with either.
I went to claude and it's gaslighting me.
Google isn't helpful either.
My people of math please help.
