8x - 8y = 1
Add 8y to each side:
8x = 8y + 1
Subtract 1 from each side:
8x - 1 = 8y
Divide each side by 8:
y = x - (1/8)

No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a solution.
8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
Rewrite the equation in the slope intercept form: y = mx + c Thus: 4x - 8y = 12 8y = 4x - 12 y = 4/8x - 12/8 = 1/2x - 3/2 and then, the gradient is the coefficient of x viz 1/2 or 0.5
The answer to that is a graph, which I cannot show you (it's not possible on this text box). I will tell you the function form of the problem: y= -10/8x + 1/4
