5(3m+6)=-3(4m-2) and -7(k+9)=9(k-5)-14k show work those are two diffrent questions

First One: 
-5(3m+6)=-3(4m-2)
-15m-30 = -12m+6
-3m = 36
m = -12

Second:
-7(k+9)=9(k-5)-14k
-7k-63 = 9k-45-14k
-7k-63=-5k-45
-2k=18
k=-9

1.   -5(3m+6) = -3(4m-2)

We must open the parenthesis and multiply every term inside the parenthesis by the number outside the parenthesis so :

   -5*3m - 5*6 = -3*4m - 3*(-2)

   -15m - 30 = -12m +6   | +12m 

   -15m +12m -30 = 12m+12m + 6

   -3m - 30 = 6  | +30
    -3m - 30 + 30  = 6+30

   -3m = 36 

   m = -36÷3

   m = -12

2.   -7(k+9)=9(k-5)-14k


Here we'll do the same thing : 
 
   -7*k - 7*9 = 9*k - 9*5 - 14k 

   -7k - 63 = 9k - 45 -14k 

   -7k - 63 = - 5k - 45 |  + 5k
 
   -7k+5k -63 = -5k + 5k - 45

   -2k - 63 = - 45 | + 63

   -2k - 63 + 63 = -45 + 63

         -2k =  18 

           k = -18÷2

          k = -9
