Question

Answer 1

To solve this equation, we are going to move all of the k's to one side and all of the constants to the other

16 - 6k = 20 - 2k        Given

16 - 6k + 2k = 20        Add 2k to each side

-6k + 2k = 20 - 16       Subtract 16 from each side

-4k = 4                       Simplify (-6k + 2k = - 4k, 20 - 16 = 4)

k = -1                        Divide both sides by -4
