suppose u have a(x) and b(y)where a and b are constants , Multiplying a(x) by b(y) it's simply ab(xy) So if u have 2x by 2y this equals to 4xy
or
The answer is 4xy.
2x = 2 times x
2y = 2 times y
2 times x times 2 times y = 2 times 2 times x times y = 4xy
-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
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
-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
-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
