Question 487173: I need help in this exercise -12=3-2k-3k (solving multi-step)

-12 = 3 - 2k - 3k

Combine -2k - 3k as -5k

-12 = 3 - 5k

Add -3 to both sides of the equation:

-12 =  3 - 5k
 -3   -3
-------------
-15 =     -5k

Divide both sides by -5

  = 

Simplify:

 3 = 

 3 = k

--------------------

Checking:

-12 = 3 - 2k - 3k
-12 = 3 - 2(3) - 3(3)
-12 = 3 - 6 - 9
-12 = -12
