Question

step by step help please 4m − 8 = 2m

Answer 1

4m-8=2m
4m-2m=8
2m=8
m=8/2
m=4

Answer 2

You need to combine all terms with m together first.
To do that, first subtract 2m from both sides:

4m - 8 = 2m
-2m -2m
--------------
2m - 8 = 0

Now you add 8 to both sides:

2m - 8 = 0
+8 +8
--------------
2m = 8

Now divide both sides by 2 to get m by itself:

\( \dfrac{2m}{2} = \dfrac{8}{2} \)

\(m = 4\)

Solution: \(m = 4\)
