It is an equation of a line in 2 dimensions.
It cannot be simplified any further or solved since two unknown variables require two independent equations.
This means that 2y - 3 = 2y + 4 which is not possible.
x=4 y=0
Exactly (2y + 4) .
x = -4 and y = 4
x = 2y = 4
-4
2y(x+2)=
-2y=x+8 is the answer
x + 2y = x + 2y Y and X aren't compatibles.
x + 2y - 9 = 4 can be rewritten as x + 2y = 13, but this is as far as you can simplify it because you have two unknowns and one equation.
x = -2 and y = 3
x=2y-1
