Hey there! :D
We can subtract the equations from each other.
4x-3x=x
2y-2y=0
10-6=4
x=4 <== that's all we have left of the equation
Now plug that in to solve.
3(4)+2y=6
12+2y=6
2y=-6
y=-3
Solution: (4,-3)
I hope this helps!

300 cookies were ordered to start.
We can tell this because we know 12% is equal to 36. Because this is true, we can set up a proportion to solve. All proportions can be set up with the small number on top and the total on the bottom. This will help you solve for the missing number, which is in this case the total number of cookies. Let x be the total number of cookies.
Percentage/total percentage = cookies/cookies total
12/100 = 36/x
Now we can cross multiply to solve.
(100)(36) = (12)(x) ----> multiply
3600 = 12x ---> divide by 12
300 = x
N and 8 in an algebraic expression would be N/8 hope this helps you.
