How do u solve the following equation: |r|=1

vredina [299]

You're almost looking at the solution. Almost.

If it only said " r = 1 ", then that would be the solution right there.

But it says " | r | = 1 ", so there's a little more to it.

'r' can be either +1 or -1 and that equation will be a true statement.

So +1 and -1 are both solutions.
