-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
Any pair of numbers where the 'y' is 5 more than the 'x'. There are an infinite number of suitable pairs. 2y-2x=10 2y-2x+2x=10+2x 2y=2x+10 divide both side by 2. y=x+5
the answer to this problem is -2x^2y^2
-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line
2x+2y
The answer to your question is (2x + 2y)^-1 = 1/(2x + 2y)^1. When you raise a number to a negative power, you can rewrite it by dividing one by the original number with the negative sign dropped from the exponent. Because the power here is 1, you can rewrite the answer again to 1/(2x + 2y) since any number raised to the power of 1 is simply the number itself. You can't add 2x and 2y because they are two different variables.
2y = 6 4x y=3 + 2x y= 2x + 3
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
get it to y= -2y = 1 - 2x y = x - 0.5
6x-2y
X + ( 2Y - 2X - Y ) is equal to Y - X
