1. What is the solution of the system of equations shown below?
y = 3x + 7
y = x-9

If you trying to find x and y is the answer is:

x=-8 and y=-17

or

(-8,-17)

Step-by-step explanation:

First you need to subtract the two equations which becomes 2x+16=0

Now you move the 16 to the other side by subtracting 16 on both sides:

2x=-16

Now divide 2 on both sides to eliminate the 2 on 2x

x=-8

Now that you got -8 as x you can replace x on the two equations any one of them you only need to get one but I am going to use both of them to show you that it is the same:

y= 3(-8)+7

y=-17

y=-8-9

y=-17

Hope this helps!

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

answer: y=0 if that is what u r looking for
