Question

How would you solve this equation: |10-3k|=2

Answer 1

\[\pm (10 - 3k) = 2\]

10 - 3k = 2
3k = 8

k = 8/3

-10 + 3k = 2
3k = 12

k = 4

Answer 2

k = 8/3 , 4

Answer 3

|10 - 3k| = 2

or

|10 - 3k| = -2

so

-3k = 2 - 10

-3k = -8

-k = -8/3

8/3 = k

or

10 - 3k = -2

-3k = -2 -10

-3k = -12

-k = -4

4 = k
