You can put this solution on YOUR website! x = 3-3y
x +3y = -6
.
rearrange the first equation
.
x + 3y = 3
.
Hmmm. That's doesn't sound right.
x + 3y = 3
and
x + 3y = -6
.
Subtract the two equations and you'll find 0 = 9.
.
But, we can look at these in slope-intercept form.
.
x = 3-3y
3y +x = 3
3y = -x +3
y = -1/3x +1
.
x +3y = -6
3y = -x -6
y = -1/3x -2
.
Aha! They're parallel lines, so there is no intersection.
