Solve the system.
2x+y = 3
-2y = 14 - 6x

The solution is: (2, -1)

Step-by-step explanation:

First we rewrite the second system equation

  →  

Now we have the following system of equations:

To solve the system multiply the first equation by -3 and add it to the second equation

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

Now we substitute the value of y in the first equation and solve for x

The solution is: (2, -1)

For this case we have the following system of equations:

We clear "y" from the second equation:

We substitute in the first equation:

So:

The solution is:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
