9+5k=45+2k
I don't even know where to begin with this. Can someone give me some direction please.
subtract 9 from each side.
subtract 2k from each side
ok I came up with 12 is that correct?
Yes. k = 12
thank you both for the help.
You're welcome.
Sure! Let's first simplify the equation and isolate the variable "k" on one side. Here's how you can do it step-by-step:
1. The equation is: 9 + 5k = 45 + 2k
2. First, let's get all the terms with "k" on one side of the equation. To do this, subtract 2k from both sides of the equation:
(9 + 5k) - 2k = (45 + 2k) - 2k
Simplifying this gives you: 9 + 3k = 45
3. Next, let's isolate the "k" term by subtracting 9 from both sides of the equation:
(9 + 3k) - 9 = 45 - 9
Simplifying this gives you: 3k = 36
4. To solve for "k," divide both sides of the equation by 3:
(3k) / 3 = 36 / 3
Simplifying this gives you: k = 12
So the solution to the equation 9 + 5k = 45 + 2k is k = 12.
