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)

y=16 x= -4

2x = 2y + 3 So 2y = 2x - 3 and y = x - 1.5 It is not possible to solve a single linear equation in two variables, other than to express one variable in terms of the other.

A single linear equation in two variables cannot be solved.

2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.
