<h2>Answer:</h2>

There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\

Now we will solve for y using what we got for x.

2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0

Solution:

A: (0, 3)

-y+8y=?<br> What is the answer please?
Tpy6a [65]

Answer:

y = -6/7

x = 6/49

Step-by-step explanation:

-7x -y = 0

7x +8y = -6

Add the two equations together to eliminate x

-7x -y = 0

7x +8y = -6

-----------------------

   7y = -6

Divide by 7

7y/7 = -6/7

y = -6/7

Now we need to find x

-7x -y = 0

-7x -(-6/7) =0

-7x +(6/7) =0

-7x +6/7 -6/7 =0-6/7

-7x = -6/7

Divide each side by -7

-7x/-7 = -6/7 *-1/7

x = 6/49
