Answer: Buying them for the year- 300 dollars
Step-by-step explanation:
30 x 12 is equal to 360 dollars, which is more expensive than 300 dollars.
x + y = 4
x − y = 6
Answer:
x=5 , y= -1
Step-by-step explanation:
You can see that one of the y's is negative while the other is positive, so you can add them together.
Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.
Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.
You can simplify that into x=5. This gives you the answer for x
Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.
Simplified, y= -1
Therefore, x= 5 and y=-1
Answer:
(5,-1)
Step-by-step explanation:
Got it right on edge cause of the guy above me
1- y(y + 5) = 750
2- y^2 – 5y = 750
3- 750 – y(y – 5) = 0
4- y(y – 5) + 750 = 0
5- (y + 25)(y – 30) = 0
y = 2x + 1
What is the solution to the system of equations?
(8, 17) (−8, 17) (−8, −17) (8, −17)

Hi Brainiac
y=3x-7
y=2x+1
We need to solve y=3x-7 for y
Now let's start by substitute 3x-7 for y in y=2x+1
y=2x+1
3x-7=2x=1
Now add -2x
3x-7-2x=2x+1-2x
x-7=1
Add 7
x-7+7=1+7
x=8
Our last step is to substitute 8 for x in y=3x-7
y=3x-7
y=(3)(8)-7
y= 24-7
y= 17
