The answer is an infinite set of points on a straight line. The exact equation of the straight line depends on the symbol thyat should appear between x and 2y which is invisible because of the inadequacies of the browser used by this site.
Unfortunately, limitations of the browser used by WA means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.
This means that 2y - 3 = 2y + 4 which is not possible.
x = -4 and y = 4
x=4 x=4
x - 2y = 4 Add 2y to both sides: x = 4 + 2y Subtract 4 from both sides: x - 4 = 2y Divide both sides by 2: (x - 4)/2 = y or y = 0.5x - 2
3x + 2y = 4; 2x - 2y = 16 Add; 5x = 20 so x = 4 and y is therefore -4
This means that 2y - 3 = 2y + 4 which is not possible.
x=4 y=0
x = -4 and y = 4
x=4 x=4
-4
Exactly (2y + 4) .
x - 2y = 4 Add 2y to both sides: x = 4 + 2y Subtract 4 from both sides: x - 4 = 2y Divide both sides by 2: (x - 4)/2 = y or y = 0.5x - 2
3x + 2y = 4; 2x - 2y = 16 Add; 5x = 20 so x = 4 and y is therefore -4
x + 2y - 9 = 4 can be rewritten as x + 2y = 13, but this is as far as you can simplify it because you have two unknowns and one equation.
x= 3 and y = 2
Put in function form. - 2X + 2Y = 4 2Y = 2X + 4 Y = X + 2 -------------set to 0 X + 2 = 0 X = -2 --------------X intercept
First, write out the problem: x+2y=4 then you have to simplify it so that only y is on one side x+2y=4 -4 -4 x+2y-4=0 -2y -2y x-4=-2y / -2 = -1/2x + 2 = y then, draw out a graph: and, let's say, x=4, then you plug that into the equation, and solve for y in this case, if x=4, then y=0, so one of the points would be (4, 0)
