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.

y=16 x= -4
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.
If: -4x+2y = 9 Then: 2y = 4x+9 Divide all terms by 2: y = 2x+4.5 which is now in slope intercept form
