Question

When solving an equation with the variable on each side, it does not really matter which side the variable ends up on once it is isolated. Why do you have to be more careful with inequalities in this situation?

Answer 1

give me an example

Answer 2

in inequalities it matters

Answer 3

y=x and y=x is is a property i forget the name but both are same

x>y and y>x is wrong

Answer 4

because while for example \(x=9\) is the same as \(9=x\)
\(x<9\) is exactly the opposite of \(9<x\)

Answer 5

Doesn't really matter if it's basic math.

Answer 6

When you deal with inequalitites you have to switch the signs around everytime you divide by a negative at least that one part counts \[\Large -2x \ge-2=~~~~~~x \le 1\]

Answer 7

I don't think shes referring to logical implication

Answer 8

That is in logic ^^^

Answer 9

@Jack172 Logic is a part of math.
Expand your horizon.

Answer 10

Primer, first of all this question isn't about mathematical logic, second what is and isn't part of mathematics is a matter of opinion, there is no fine line between what is and isn't though I would agree that logic is a part of mathematics.

Answer 11

@Jack172 how come every question you're getting into an argument? Lol
