Simultaneous equations
-2x + y = -3
-x + 2y = 3
Multiply the bottom equation by '-2'
Hence
-2x + y = -3
2x - 4y = -6
Add the two equations
-3y = -9
Divide both sides by '-3'
y = (+)3
Substitute in to either equ'n for 'x'
-2x + 3 = -3
Subtract '3' from both sides
-2x = -6
Divide both sides by '-2'
x = (+)3
Hence (x,y) = ( 3,3)
