Multiply entire first equation by 3 so the y variables will cancel when you add the equations.

6x +3y =-12
5x -3y =1

Add the equations.

11x =-11
X=-1

Now use that value for x in either equation to find y.

2(-1) +y= -4
-2+y =-4
Y =-2

Solution is (-1, -2)

Answer:

For the first equation the answer for "X" will be,

x =  \frac{ - 4 - y}{2}

if you want me to solve for y instead then the answer will be,

y =  - 4 - 2x

for the second equation the answer for "X" will be,

x =  \frac{1 + 3y}{5}

If you want me to solve for y instead then the answer will be,

y =  -  \frac{1 - 5x}{3}
