There is an infinite amount of answers because you have to give x or y a value before solving for the other variable. Examples: x=1, y=24.418717, or, x=53.8375635, y=1. Both would be correct.

I assume you mean rearrange the equation so y is the only thing on one side. Solving this equation for a numerical value of x and y would require a second equation.
To change 197x + 394y = 11,000 into the form y=?, here is what I would do:
Subtract 197x from each side, so now 394y = 11,000 - 197x
Next, divide both sides by 394: y = 27.91878173 - 0.5x

there is an unlimited number of answers, but here is what I think you are asking for :
solve for x
197x+394y=11,000 (subtract 394y)
197x=11,000 - 394y (divide by 197)
x=(11,000-394y)/197
now put in values for y, then you get X to find both coordinates for the line.
solve for y
197x+394y=11,000 (subtract 197x)
394y=11,000-197x (divide by 394)
y=(11,000-197x)/394
now put in values for x, then you get Y to find both coordinates for the line.
hint (the lines better be the same) :)

This equation has infinite solutions because it is the equation of a line. For any x one assigns, there is a unique y and visa versa. For example, if we let x be 0, then y = 11,000 / 394. If we let y = 0, then x = 11,000 / 197.

x = (11,000 - 394y)/197
or
y = (11,000 - 197x)/394

Hey,
Are you trying to differentiate in terms of y?
If so... differntiate the equation.
197 + 394 dy/dx = 0
collect like terms:
394 dy/dx = -197
dy/dx = -197/394
figure out the answer and that's how you differentiate in terms of y.

x + 2y = 11000/197
y = 5500/197 - x/2
Solving for y, you now plug in values for x and you will see the y .
This is about all you can do for this type of equation

You have two variables, but only one equation. Depeding of if you are solving for y or x, you will an unknown in each answer.

You need a minimum of one equation per variable, so we need a second equation to solve this...

the equation can not be solved because there are two unknow variables.
