Question

3(K-2)=15
How do I solve for K

Answer 1

Answer:

7

Step-by-step explanation:

step 1. divide 15 by 3

(K-2)=5

step 2. add the 2 to the 5

K=7

Answer 2

Answer: k = 7

Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.

3(k) is 3k and 3(-2) is -6.

So we have 3k - 6 = 15.

Next, isolate the k term by adding 6 to both

sides of the equation and we get 3k = 21.  

Now divide both sides by 3 and k = 7.

If you want, you can check your answer by plugging a 7

back into the original equation to see if it works.
