Answer:
k = -1/2 or -0.5
Step-by-step explanation:
4k - 11 + 15 = 2
First of all, you need to move the -11 and +15 to the right hand side, to remain 4k
4k -11 + 15 = 2
+11 -15 +11 - 15
You end up with,
4k = 2 + 11 -15
The numbers on the right hand side can make a sum of 2 + 11 - 15 = 13 - 15 = -2
4k = -2
Divide the 4 by the -2
k = -2/4
k = -1/2
This can be written as -0.5 as well
