what's the common solution for

Question

4x+3=y....     -2y=8x-2

Answer 1

lets use elimination

 

multiple the first equation by (-2)

-8x-6=-2y

 

2nd equation is 

8x-2=-2y

 

add these together 

-8=-4y and solving for y, yields  : y=2

 

substituting back into either of the equations yields x

4x+3=(2)

4x=-3+2=-1,    so x = -1/4
