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
