Question

Solve: 9m + 12 = 15Solve: 9m + 12 = 15

Answer 1

Solution

Solve the equation

$9m+12=15$

Step 1: Subtract 12 from both side

$\begin{gathered} 9m+12=15 \\ 9m+12-12=15-12 \\ 9m=3 \end{gathered}$

Step 2: Divide both side by 9

$\begin{gathered} 9m=3 \\ m=\frac{3}{9} \\ m=\frac{1}{3} \end{gathered}$

Hence the solution for m = 1/3

Therefore the correct answer is Option B
