In this question we have to find the value of K.
Explanation:
The first step while solving these problems is to take the like terms on each side ie. terms with K on one side and the numbers on the other side.
2-7K= -K +20
-7K + K = 20 - 2
This will give me,
-6K = 18
Note, here that I have used -ve sign before 6K because whenever we are solving an equation we use the sign and operation which the bigger value of coefficient has ie. here 7 was bigger than 1 and it had a -ve sign before it so I subtracted the two and added a -ve sign before 6.
Now to find the value of K I will divide both the sides with -6. That will give me:
K= -3
