How do you solve the equation #130=11k+9#?

Answer 1

See a solution process below:

First, subtract #color(red)(9)# from each side of the equation to isolate the #k# term while keeping the equation balanced:

#130 - color(red)(9) = 11k + 9 - color(red)(9)#

#121 = 11k + 0#

#121 = 11k#

Now, divide each side of the equation by #color(red)(11)# to solve for #k# while keeping the equation balanced:

#121/color(red)(11) = 11k/color(red)(11)#

#11 = color(red)(cancel(color(black)(11)))k/cancel(color(red)(11))#

#11 = k#

#k = 11#

#k = 11#

Make #k# the subject of the equation as explained below:

#130=11k+9#

Subtract #130# both sides:

#130-130 = 11k + 9 -130#

#0=11k+9-130#

Subtract #11k# both sides:

#0-11k = -121#

#-11k = -121#

#k= -(121/-11)#

#k = 11#

Verify the response:

#130 = 11(11) +9# #130 = 121+9#

To solve the equation 130 = 11k + 9, you first subtract 9 from both sides to isolate the term with the variable: 130 - 9 = 11k. This simplifies to 121 = 11k. Then, you divide both sides by 11 to solve for k: 121 / 11 = k. This gives you k = 11. So, the solution to the equation is k = 11.

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.
