26=5-7k i just need to remember how to do these types of problems, please tell me how to work these out

-3=k

Step-by-step explanation:

First you have to remove the numbers that are in the side of the variable,by changing them with the opposite from both sides

26-5=5-7k-5

21=-7k

now you have to divide both sides by the number the variable is next to

21/-7=-7k/-7

-3=k

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
