Let's build the equation counting how many x's and 1's are there on each side.
On the left hand side we have 5x's and 8 1's, for a total of 
On the left hand side we have 3x's and 10 1's, for a total of 
So, the equation we want to solve is
Subtract 3x from both sides:
Subtract 8 from both sides:
Divide both sides by 2:
-k-(-8k)
= -k + 8k (two negatives equal one positive)
= 8k-k (flip it around because of the commutative property)
=7k (basic subtraction)
I really hope that helped :)

Answer:
see below
Step-by-step explanation:
m²+8m=0
Factor out an m
m(m+8) =0
Using the zero product property
m=0 m+8 =0
m =0 m=-8
