Question

m - 12.39 = 29.76

Explanation:

Step1: Isolate the variable \( m \)

To solve for \( m \), we need to add \( 12.39 \) to both sides of the equation \( m - 12.39 = 29.76 \) to isolate \( m \). This is based on the addition property of equality, which states that if we add the same number to both sides of an equation, the equation remains true.

$$ m - 12.39 + 12.39 = 29.76 + 12.39 $$

Step2: Calculate the sum

Now we calculate the sum on the right side. \( 29.76 + 12.39 = 42.15 \). So we have:

$$ m = 42.15 $$

Answer:

\( m = 42.15 \)
