Answer:
m = 2
Step-by-step explanation:
First we must distribute on both sides of the equation. If we distribute the 5 on the left we should end up with,
-20m + 10 = -2(3 + 6m)
Then we can distribute the right side,
-20m + 10 = -6 - 12m
We want to move the m's to one side so let's move the -20m to the right by adding it to both sides.
-20m + 10 + 20m = -6 - 12m + 20m
This gives us,
10 = -6 + 8m
Finally we want to move the -6 over to the left by adding it to both sides.
10 + 6 = 8m
16 = 8m
From here we divide both sides by 8 to get m alone.
m = 2

Let's solve ~
Cost price for each Orange :
![\qquad \tt \dashrightarrow \: \dfrac{60}{200}](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A%20%5Cdfrac%7B60%7D%7B200%7D%20)
![\qquad \tt \dashrightarrow \:0.3 \: \: kobo](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A0.3%20%5C%3A%20%20%5C%3A%20kobo)
Now, Cost price for 8 oranges :
![\qquad \tt \dashrightarrow \:0.3 \times 8](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A0.3%20%5Ctimes%208)
![\qquad \tt \dashrightarrow \:2.4 \: \: kobo](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A2.4%20%5C%3A%20%20%5C%3A%20kobo)
And we have been given that selling price for 8 oranges is 12 kobo.
Therefore, the gain is :
![\qquad \tt \dashrightarrow \:12 - 2.4](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A12%20-%202.4)
![\qquad \tt \dashrightarrow \:9.6 \: \: kobo](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A9.6%20%5C%3A%20%20%5C%3A%20kobo)
Percentage gain is ~
![\qquad \tt \dashrightarrow \: \dfrac{9.6}{2.4} \times 100](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A%20%5Cdfrac%7B9.6%7D%7B2.4%7D%20%20%5Ctimes%20100)
![\qquad \tt \dashrightarrow \:4 \times 100](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A4%20%5Ctimes%20100)
![\qquad \tt \dashrightarrow \:400 \: \%](https://tex.z-dn.net/?f=%5Cqquad%20%5Ctt%20%5Cdashrightarrow%20%5C%3A400%20%5C%3A%20%20%5C%25)
