8 0

Answer:

y=-6 and x=0

Step-by-step explanation:

-4x -2y = -12

4x + 8y = -24

(add the equations)

6y = -36

-36/6 = -6

y=-6

(Add y value in any of the equations)

-4x-2(6) = -12

-4x-12=-12

-4x=0

x=0

Solve |3k-2|=2|k+12|
Stella [2.4K]

Answer:

k = 26   or   k = -\dfrac{22}{5}

Step-by-step explanation:

|3k - 2| = 2|k + 12|

\dfrac{|3k - 2|}{|k + 12|} = 2

|\dfrac{3k - 2}{k + 12}| = 2

3k - 2 = 2(k + 12)   or   3k - 2 = -2(k + 12)

3k - 2 = 2k + 24   or   3k - 2 = -2k - 24

k = 26   or   5k = -22

k = 26   or   k = -\dfrac{22}{5}
