Question

4m-4=4m solve this equation. prefer an explanation.

Answer 1

It's impossible, unless infinity is an answer.

Answer 2

-4 \[\neq\] 0

Answer 3

4m = 4m + 4
0 = 4

Answer 4

Impossible

Answer 5

we can start by getting rid of all the 4s; they are a scaled version of:

m-1 = m

Answer 6

then notice that nothing fits :)

Answer 7

4=0, where 4 is an unreal number

Answer 8

of course this assumes that we are using standard mathematical notation

Answer 9

So we have 4m - 4 = 4m.
If we factor out a 4, we have:
4(m-1) = 4m.
But this does not help.
4m-4 = 4m.
Subtracting 4 m from both sides, we have:
-4 = 0m
Division by zero is not permitted, so we have 0 = -4 which without using the complex number system is impossible, so the answer for a typical algebra course would be either infinity or no solutions.
Hope this helps.
