6k + 2 = 8
Isolate the 8. Do the opposite of PEMDAS.
Note the equal sign. What you do to one side you do to the other.
Subtract 2 from both sides
6k + 2 (-2) = 8 (-2)
6k = 8 - 2
6k = 6
Isolate the k, divide6 from both sides.
6k/6 = 6/6
k = 6/6
k = 1
1 is your answer.

Step-by-step explanation:
-7x + 2y = 18
6x + 6y = 0
21x - 6y = - 54
6x + 6y = 0
27x = -54
x = -2
6(-2) + 6y = 0
-12 + 6y = 0
6y = 12
y = 2
