solve linear system using and algebraic method 3x+ 3y = 3 y=-x

OpenStudy (anonymous):

$3x+3(-x)=3$$3(-y)+3y=3$ Then simplify.

3x-3x=3 0=3 ????? No solutions

OpenStudy (anonymous):

wait so whats the right answer?

The right answer is there is no answer. I guess you could say y can not be equal to -x.

OpenStudy (anonymous):

if $x=-y$ then $3x+3y=0$

OpenStudy (anonymous):

for example if $x=4$ then $y=-4$ and $3\times 4+3\times -4=12-12=0$ so you cannot get 3 out of it

OpenStudy (anonymous):

It's a system with no solution, since 3 cannot equal zero.

okay thank you
