=(1000000-x)*(1+y)

Solution for =(1000000-x)*(1+y) equation:

Simplifying
0 = (1000000 + -1x)(1 + y)

Multiply (1000000 + -1x) * (1 + y)
0 = (1000000(1 + y) + -1x * (1 + y))
0 = ((1 * 1000000 + y * 1000000) + -1x * (1 + y))
0 = ((1000000 + 1000000y) + -1x * (1 + y))
0 = (1000000 + 1000000y + (1 * -1x + y * -1x))
0 = (1000000 + 1000000y + (-1x + -1xy))

Reorder the terms:
0 = (1000000 + -1x + -1xy + 1000000y)
0 = (1000000 + -1x + -1xy + 1000000y)

Solving
0 = 1000000 + -1x + -1xy + 1000000y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.
0 + x = 1000000 + -1x + -1xy + x + 1000000y
Remove the zero:
x = 1000000 + -1x + -1xy + x + 1000000y

Reorder the terms:
x = 1000000 + -1x + x + -1xy + 1000000y

Combine like terms: -1x + x = 0
x = 1000000 + 0 + -1xy + 1000000y
x = 1000000 + -1xy + 1000000y

Add 'xy' to each side of the equation.
x + xy = 1000000 + -1xy + xy + 1000000y

Combine like terms: -1xy + xy = 0
x + xy = 1000000 + 0 + 1000000y
x + xy = 1000000 + 1000000y

Reorder the terms:
-1000000 + x + xy + -1000000y = 1000000 + 1000000y + -1000000 + -1000000y

Reorder the terms:
-1000000 + x + xy + -1000000y = 1000000 + -1000000 + 1000000y + -1000000y

Combine like terms: 1000000 + -1000000 = 0
-1000000 + x + xy + -1000000y = 0 + 1000000y + -1000000y
-1000000 + x + xy + -1000000y = 1000000y + -1000000y

Combine like terms: 1000000y + -1000000y = 0
-1000000 + x + xy + -1000000y = 0
