Question

Can we multiply every term of an equation by anything we want? How about an expression?

I need examples!

Answer 1

as long as you do it to all of it, sure

Answer 2

What about an expression?

Answer 3

you can multiply an expression by anything you want to...
but it will change it if you multiply by anything other than one

Answer 4

So but its legal to multiply an expression by (5) if not indicated?

Answer 5

that will be a completely different value (5 times bigger)
multiply by 5/5 and both expressions will have the same value (you multiplied by 1)

Answer 6

Ok, just to make sure in an equation:

You can multiply for whatever you want, as long as you do it on both sides.
On expression you can't

Answer 7

an expression doesn't have two sides to it

Answer 8

Exactly...
