Answer:
k=-9
Step-by-step explanation:
k-8+8=-17+8
k=-9
We have the following:

solving for x

The solution of x is equal to 28, therefore 12 is not a solution of the equation
Answer:
x=8
Step-by-step explanation:
7+5x
so basically what you have to do is take the 7 and subtract from both sides
so like this: 7-7 is 0 so that cancels then 47-7 is 40
then you take 5x and divide 40 by 5
so x=8
hope this helped!
