Solution
Solve the equation
[tex]9m+12=15[/tex]
Step 1: Subtract 12 from both side
[tex]\begin{gathered} 9m+12=15 \\ 9m+12-12=15-12 \\ 9m=3 \end{gathered}[/tex]
Step 2: Divide both side by 9
[tex]\begin{gathered} 9m=3 \\ m=\frac{3}{9} \\ m=\frac{1}{3} \end{gathered}[/tex]
Hence the solution for m = 1/3
Therefore the correct answer is Option B
