To solve the equation \( 7308:(m-589)=12 \), we can rewrite it in a more standard form:
\[ \frac{7308}{m - 589} = 12 \]
Now, we can cross-multiply to eliminate the fraction:
\[ 7308 = 12(m - 589) \]
Next, distribute the 12 on the right side:
\[ 7308 = 12m - 7068 \]
Now, to isolate the term with \( m \), add 7068 to both sides:
\[ 7308 + 7068 = 12m \]
\[ 14376 = 12m \]
Now, divide both sides by 12 to solve for \( m \):
\[ m = \frac{14376}{12} \]
Calculating that gives:
\[ m = 1198 \]
So the solution is:
\[ m = 1198 \]
