"Four X plus five Y is equal to negative seventeen" is not a question. It's a
statement of fact.
Since the statement deals exclusively with algebraic quantities and operations, it
can be written and viewed as a mathematical equation, and questions regarding
the equation and its implications may be formulated. But so far, we have nothing
here that's looking for an answer.

y = (11-4x)/5
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
If: 4x = 5y Then: x = 5y/4

If: 20x+5y = 15 Then: y = -4x+3
y = (11-4x)/5
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form

6x plus 3y minus 2x plus 5y equals 4x plus 8y.
If: 4x = 5y Then: x = 5y/4

4x+5y = 30 5y = -4x+30 y = -4/5x+6 in slope intercept form So the y intercept is 6.
