Welcome to Brainly! :)
I cannot understand your equation, therefore I have put it as 36x + 8y + 2. If I'm wrong let me know and I'll fix everything. :)
We need to plug in our values for what we are given.
Let us learn about plugging in.
Let's start with an example equation:
1x + 3y + 1 - Values: y = 2, x = 4 This is a simple equation.
- When it tells you to plug in or tell you the values, that's your ket to plug in the variable for what it tells you.
Now, let's solve this example, our equation is:
1(4) + 3(2) + 1
Now, we have the original equation but plugged in. Next we simplify:
4 + 6 + 1
Add it up and get 11.
Great! Now that we are done with notes, we can solve.
36x – 8y + 2
It tells us that x = 3 an y = 6. Like the equation, we need to plug it in.
Great, now we need to simplify.
Cool, now we simplify and get 128!
Great job!
I hope you had amazing experience with brainly! :D
