well, if 5-y=x, then y=x+5. basically that is only used for graphing.
If you are graphing speed over a period of time, speed goes on the y-axis and time goes on the x-axis.
You cannot solve x plus y since that is an expression, not an equation (nor inequality).
By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations

In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
x-y=4 x=y+4

(x,y) (-x,-y)
x
Ordered pairs are used in graphing, with the x axis first in the pair. Example: (5,7) (x,y)
Set it equal to 0 and subtract x and solve for y
You cannot solve x plus y since that is an expression, not an equation (nor inequality).

Same thing as they do when you are graphing.
The x axis is read first when plotting points in the form (x,y) on the xy-plane.
