Question

1.    x+3Y=-3

 

 

2.   _   2

         _x_     =-1

           y

Answer 1

x + 3y = -3

 

-2x/y = -1

 

Solving the second equation for y:

 

-2x = -y

 

2x = y <--- multiplies both sides by -1

 

Substitutes this new equation into the first

 

x + 3(2x) = -3

 

x + 6x = -3

 

7x = -3

 

x = -3/7

 

y = 2x = 2(-3/7) = -6/7

 

Check:

 

 (-3/7) + 3(-6/7) = -3/7 + (-18/7) = -21/7 = -3

 

-2x/y = -2(-3/7)/(-6/7) = (6/7)/(-6/7) = -1

 

The second equation is not entirely clear.

Feel free to re-post.

 

But as written and interpreted,

x = -3/7

y =-6/7

 

and these answers are CHECKED and PROVEN to be correct.
