Answer:
K = 6 X = -11
Step-by-step explanation:
38+7k=8(k+4) 3(1-3x)=2(-4x+7)
38 + 7k = 8k + 32 3 - 9x = - 8x + 14
- 7k -7k - 3 - 3
-------------------------- ----------------------------
38 = k + 32 - 9x = - 8x + 11
- 32 - 32 + 8x + 8x
-------------------------- -----------------------------
k = 6 - 1x = 11
----- ------
-1 -1
------------------------------
x = -11
