Sounds like 2 parallel lines.


Consider


2x-3y = 5

and

2x-3y = 7


These lines have the same slope and are thus parallel. Parallel lines never intersect. So there is no algebraic or graphical solution.

`

We'll set up the first two equations so z=1 and the last so it doesn't, no solutions.



x + y + z = 1


x + y + 2z = 2


z = 0

Help ^^^ use picture above
aalyn [17]
The question reminds you of all the tools you need:

It says ...

"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.

And it says ...

"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then
use that to find the size of every angle.
