Question

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

Answer 1

\[3x+3(-x)=3\]\[3(-y)+3y=3\]

Then simplify.

Answer 2

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

Answer 3

wait so whats the right answer?

Answer 4

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

Answer 5

if
\[x=-y\] then
\[3x+3y=0\]

Answer 6

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

Answer 7

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

Answer 8

okay thank you
