(6, -2)
  x   y

plug them in, see if they work

whpalmer4 · Answer

Plug in the values and see what happens.

Note that all of the equations must work, not just some of them!

yes they do

anonymous · Answer

2x - 3y = 18 (1)
5x + 3y = 3  (2)
Substitute x = 6 and y = -2 into the 2 equations
The top equation (1) is satisfied with (6, -2)
The bottom equation (2) isn't.
Then, the answer is......
