How do you solve the equation # 5 + c/9 = -31#?

Answer 1

#c=-324#

First, get all the variables on one side of the equation and everything else on the other side. In this case, you subtract 5 from both sides to get #c/9=-36#.

Then solve for #c# by multiplying both sides by 9 and get #c=-324.#

Now to check your work, you can plug -324 in for #c# and that will equal the right side, #-31#: #5+(-324)/9=-31#

#c=-324#

#5+c/9=-31 " "# Subtract 5 on both sides to get

#c/9=-36 " "# Multiply by 9 on both sides to get

#c=-324 " "#

Check using substitution: #5+(-324)/9=-31 " "#

#5-36=-31 " "#

#-31=-31 " "#

Since we get a true statement, we know we have the correct solution!

To solve the equation 5 + c/9 = -31, you first subtract 5 from both sides to isolate c/9, resulting in c/9 = -36. Then, multiply both sides by 9 to solve for c, yielding c = -324.

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.
