Let's simplify it ... (4y-2x) = 0 = (2y -x ) = 0 2y = x y = x/2 Yes, it is linear.

if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola

Isolate one of the variable using inverse operations. Then solve. Example: 2x + 4y = 0 --subtract 4y>> 2x = -4y --divide by -4>> -1/2x = y --plug in your variable -->>

Convert the function into the general form y = mx + c, where 'm' is the slope. 2x + 4y = 8 : 4y = -2x + 8 : y = -x/2 + 2 : The slope is therefore -1/2.

2x + 4y = 72x - 2x + 4y = 7 - 2x4y = -2x + 74y/4 = -2x/4 + 7/4y = -(1/2)x + 7/4Now that y is a function of x, you can give some values for x and find the corresponding values for y. (There are infinitely values for x an y)

2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)

If you mean: 2x+4y = 4 then the graph joins the points: (2, 0) and (0, 1)

I assume that is 2x - 4y = 10 The x-intercept is when y = 0: 2x - 4 x 0 = 10 → 2x = 10 → x = 5.

10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y

Add 2x to each side: 4y = 2x Divide each side by 2: 2y = x So any two numbers where one is twice the other will be a solution.

2x - 4y = 8 2x = 4y + 8 x = 2y + 4
