90=(x-2)(y-1.5)

Solution for 90=(x-2)(y-1.5) equation:

Simplifying
90 = (x + -2)(y + -1.5)

Reorder the terms:
90 = (-2 + x)(y + -1.5)

Reorder the terms:
90 = (-2 + x)(-1.5 + y)

Multiply (-2 + x) * (-1.5 + y)
90 = (-2(-1.5 + y) + x(-1.5 + y))
90 = ((-1.5 * -2 + y * -2) + x(-1.5 + y))
90 = ((3 + -2y) + x(-1.5 + y))
90 = (3 + -2y + (-1.5 * x + y * x))
90 = (3 + -2y + (-1.5x + xy))

Reorder the terms:
90 = (3 + -1.5x + xy + -2y)
90 = (3 + -1.5x + xy + -2y)

Solving
90 = 3 + -1.5x + xy + -2y

Solving for variable 'x'.

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

Add '1.5x' to each side of the equation.
90 + 1.5x = 3 + -1.5x + xy + 1.5x + -2y

Reorder the terms:
90 + 1.5x = 3 + -1.5x + 1.5x + xy + -2y

Combine like terms: -1.5x + 1.5x = 0.0
90 + 1.5x = 3 + 0.0 + xy + -2y
90 + 1.5x = 3 + xy + -2y

Add '-1xy' to each side of the equation.
90 + 1.5x + -1xy = 3 + xy + -1xy + -2y

Combine like terms: xy + -1xy = 0
90 + 1.5x + -1xy = 3 + 0 + -2y
90 + 1.5x + -1xy = 3 + -2y

Add '-90' to each side of the equation.
90 + 1.5x + -90 + -1xy = 3 + -90 + -2y

Reorder the terms:
90 + -90 + 1.5x + -1xy = 3 + -90 + -2y

Combine like terms: 90 + -90 = 0
0 + 1.5x + -1xy = 3 + -90 + -2y
1.5x + -1xy = 3 + -90 + -2y

Combine like terms: 3 + -90 = -87
1.5x + -1xy = -87 + -2y

Reorder the terms:
87 + 1.5x + -1xy + 2y = -87 + -2y + 87 + 2y

Reorder the terms:
87 + 1.5x + -1xy + 2y = -87 + 87 + -2y + 2y

Combine like terms: -87 + 87 = 0
87 + 1.5x + -1xy + 2y = 0 + -2y + 2y
87 + 1.5x + -1xy + 2y = -2y + 2y

Combine like terms: -2y + 2y = 0
87 + 1.5x + -1xy + 2y = 0
