2y = 4x + 4y = 2x + 2

many solutions

get it to y= -2y = 1 - 2x y = x - 0.5

The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).

y=16 x= -4

Solve for y: 2x+2y=8 2y=-2x+8 y=-x+4 f(x)=-x+4 I think that's what you mean.

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.

-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x

A single linear equation in two variables cannot be solved.

-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5

X + ( 2Y - 2X - Y ) is equal to Y - X

x+2y-2x-y=x y-x=x y=2x
