How do you find the solution of the system of equations #x+y= -3# and #x+y=3#?

Answer 1

There are no solutions to this pair of equations. These equations represent two parallel lines (both with slope #(-1)#) which share no points in common.

The system of equations x + y = -3 and x + y = 3 has no solution because the two equations represent parallel lines with the same slope but different y-intercepts, meaning they never intersect.

Answer 3

Eva Abramson

The system of equations x + y = -3 and x + y = 3 does not have a solution because the two equations represent parallel lines with the same slope but different y-intercepts. Since parallel lines never intersect, there is no point that satisfies both equations simultaneously. Therefore, the system is inconsistent and has no solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
