Question

Difficulty: EasySolving One-Variable Linear Equations
What value of mm makes the equation 12m−7=41 12m - 7 = 41 true?

Answer: 4

Answer

4
Applying the correct sequence of inverse operations (first adding 7, then dividing by 12) yields exactly 4.

Step-by-Step Solution

1
Add 7 to both sides of the equation.
12m=48 12m = 48
This is the first inverse operation needed to isolate the variable term.
2
Divide both sides by 12.
m=4 m = 4
This inverse operation isolates mm, giving the final solution.
