I don't know what K is. Do you?

if you want to find the value of K you have to isolate the value by doing operations on both side of the equation. It's a simple problem so you have to try a little harder. One hint - K is negative.

K is the variable.

5k + 18 = -7
-18 -18 [add negative plus a negative]

\5k = -25/ [negative divided by a positive = a negative]
5 5
___________
k = -5

**to check your answer place the -5 where the variable k is. Let's do it together.

5(-5)+ 18 =-7 [remember your order of operations.
1.) parenthesis
2.) exponents
3.) mulitiply
4.) divide
5.) add
6.) subtract
**to remember: the first letter in each word is
PEMDAS <that's how I remember.

-25 + 18 = -7 [-25 + 18 = -7]

-7 = -7

Now you know you're correct!

Hope this helped!
