The y value will equal 15, when x = 7
Without any equality signs the given expression can't be considered to be straight line equations.
Without a second independent equation, it's not a 'system' yet.

If you mean: y = 2x+1 then the gradient is 2 and the y intercept is 1
y2x - just double the coordinate of y to get x. xy12 - i have no idea
If you mean y = 2x and y = 2x-1 then they are parallel lines because they have the same slope.

(4,1)
Without any equality signs the given expressions can't be considered to be equations so therefore there are no solutions.
y2x is an expression, which cannot be graphed because we don't know what it equals. y = 2x, y2 = x, and 2y (or y2) = x are all things that could actually be graphed.
It is an expression in two variables, x and y.
If you mean: y = 2x-4 and (1, 5) then the parallel equation is y = 2x+3
