To multiply 2x by 2y, you would use the distributive property of multiplication over addition. This means you would multiply each term in the first expression by each term in the second expression. In this case, 2x * 2y would result in 4xy, as 2 * 2 equals 4 and x * y equals xy.
Well, isn't that just a happy little math problem we have here! To multiply 2x by 2y, you simply multiply the numbers together: 2 * 2 = 4. And then you multiply the variables together: x * y = xy. So, the result is 4xy. Just like that, you've created a beautiful mathematical expression!
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
it means two times x times y.
-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.
5x-2y+3z-2x-y-4z=3x-3y-z
2y = 4x + 4y = 2x + 2

-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
Multiply First equation by 2: 6y - 2x = 0Add second equation to this: 6y - 2x + 2x + 2y = 0 + 7Simplify: 8y = 7 so y = 0.875 and x = 2.625
it means two times x times y.
2x+2y
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
-2X + 2Y = 4 2Y = 2X + 4 Y = X +2 by inspection, 2 but, you could also 0 out X in original equation -2(0) + 2Y = 4 2Y = 4 Y = 2
