Question

What does the m in 4m-4=4m mean

Answer 1

Hello there ^ _ ^

When you have 4m - 4 = 4m
The m means that you are looking for a number, but the number is unknown and you usually need to find it.

M is like blank space.
For example : She .... two apples
The blank space can be eats. right?

well it is the same thing for M
4..-4 = 4..
The blank space is missing a letter and you need to go look for that letter or number.

Now, let me solve it for you just in case if you would like to know how to find that unknown number.

4m - 4 = 4m
You need to put the common terms together ( the common terms are the one that looks alike)
we have two 4m, right ? so we gonna put them together.
-4 = 4m - 4m
-4 = 0
Add 4 to both sides
-4+4 = 0+4
0 = 4
In this case there are no solutions.

This mean that there no number you can replace m with that will make them equal. Does that make sense ?

I hope this help! Comment if you have more questions!
