2x + y = 1
3x - y = -6
---------------add
5x = -5
x = -5/5
x = -1
2(-1) + y = 1
-2 + y = 1
y = 1 + 2
y = 3
solution is (-1,3)
That equation has no solution. There is no number that can be written in place of 'x' that makes the equation true.
20 because 12 divided by 3 is 4. then you multiply 5 by 4. and you get 20.
