Option A is the correct option
Step-by-step explanation:
Collect like terms
⇒![\sf{8m - 8 = 64}](/tpl/images/0729/6013/585b5.png)
Move 8 to right hand side and change it's sign
⇒![\sf{8m = 64 + 8}](/tpl/images/0729/6013/c4ee9.png)
Add the numbers
⇒![\sf{8m = 72}](/tpl/images/0729/6013/b115e.png)
Divide both sides of the equation by 8
⇒![\sf{ \frac{8m}{8} = \frac{72}{8} }](/tpl/images/0729/6013/bebda.png)
Calculate
⇒![\sf{m = 9}](/tpl/images/0729/6013/17dd8.png)
Hope I helped!
Best regards!!
