You cannot solve for a UNIQUE solution for the problem. As you can see, there are infinitely many solutions for x and y here. For example,
x = -2, y = 14 will work
x = -1, y = 9 will work
x = 0, y = 4 will work
x = 1, y = -1 will work
x = 2, y = -6 will work
This is an example of an equation of two variables, specifically, a LINEAR equation with 2 variables. It is "linear" because when you graph it in a rectangular coordinate system, you will have a straight line.

What exactly are you trying to do? The equation has infinite solutions because you can plug any value in for x or y and then solve for the other variable. If you are trying to graph it the slope is -5 and the y intercept is 4.

Sorry, an equation is not a problem. A problem is a question like, what is the y-intercept of the graph of the equation, or what is the slope of the graph?

Yes, just substitue all of your variables to one side. Y+5x=4 other than that you cannot solve for the variable without first knowing at least one of them.

Slope=m=-5
the y-intercept is 4
y=-5(0)+4
y=4
(0,4)
the x-intercept is this:
0=-5x+4
-5x=-4
x=4/5
(4/5,0)

slope is -5 and x intercept is 4
-5x=y-4
x=(y-4)/-5
=>(4-y)/5
