Question #10454

X+2y=2

-x+3y=13

-x+3y=13

Expert's answer

x+2y=2

-x+3y=13

Let's add the equations:

-x+x+2y+3y=2+13

5y=15 whence y=3

From the first equation we get x=2-2y

Substituting y=3 we obtain

x=2-2*3=-4

So the answer is x=-4, y=3

-x+3y=13

Let's add the equations:

-x+x+2y+3y=2+13

5y=15 whence y=3

From the first equation we get x=2-2y

Substituting y=3 we obtain

x=2-2*3=-4

So the answer is x=-4, y=3
