Solving for 'y'

2x - 2y + 5 = 0

Add 2y on both sides

2x + 5 = 2y

Divide by 2 on both sides

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

Solving for 'x'

2x - 2y + 5 = 0

Subtract 2x on both sides.

-2y + 5 = -2x

Divide 2x on both sides

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

If you are trying to graph it, then you need to simplify it to simplest linear slope form: y = mx + b

As of now, you have 2x - 2y + 5 = 0

Isolate the y to one side of the equation, -2y = -2x - 5

Divide the entire equation by -2, to completely isolate the y,
y = x + 5/2

Basically, y = x + 5/2 and x = y - 5/2
