Answer:
4
Explanation:
We first find the common denominator of all three of the fractions. Since the denominators are 2 and 4, the least common denominator (LCD) would be 4, as that is the first number both 2 and 4 go into.
1/2 is the same as 2/4; this makes the equation
-3/4m - 2/4 = 2 + 1/4m
Since all of the fractions have the same denominator, we multiply by that denominator to eliminate the fractions; multiply by 4.
