How do you solve #k + 9 = 6(k - 11)#?

Answer 1

Nathan Axel

First, simplify the equation on both sides then, isolate the variables.

#k+9 = 6k - 66#

#9+66 = 6k-k#

#5k = 75#

#k=75/5#

#k=15#

The final answer should be 15.

To solve the equation k + 9 = 6(k - 11), first distribute the 6 on the right side: k + 9 = 6k - 66. Then, subtract k from both sides to isolate k: 9 = 5k - 66. Next, add 66 to both sides: 75 = 5k. Finally, divide both sides by 5: k = 15.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
