Solution for (x-20)(y-4z)= equation:


Simplifying
(x + -20)(y + -4z) = 0

Reorder the terms:
(-20 + x)(y + -4z) = 0

Multiply (-20 + x) * (y + -4z)
(-20(y + -4z) + x(y + -4z)) = 0
((y * -20 + -4z * -20) + x(y + -4z)) = 0
((-20y + 80z) + x(y + -4z)) = 0
(-20y + 80z + (y * x + -4z * x)) = 0
(-20y + 80z + (xy + -4xz)) = 0

Reorder the terms:
(xy + -4xz + -20y + 80z) = 0
(xy + -4xz + -20y + 80z) = 0

Solving
xy + -4xz + -20y + 80z = 0

Solving for variable 'x'.

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

Add '20y' to each side of the equation.
xy + -4xz + -20y + 20y + 80z = 0 + 20y

Combine like terms: -20y + 20y = 0
xy + -4xz + 0 + 80z = 0 + 20y
xy + -4xz + 80z = 0 + 20y
Remove the zero:
xy + -4xz + 80z = 20y

Add '-80z' to each side of the equation.
xy + -4xz + 80z + -80z = 20y + -80z

Combine like terms: 80z + -80z = 0
xy + -4xz + 0 = 20y + -80z
xy + -4xz = 20y + -80z

Reorder the terms:
xy + -4xz + -20y + 80z = 20y + -20y + -80z + 80z

Combine like terms: 20y + -20y = 0
xy + -4xz + -20y + 80z = 0 + -80z + 80z
xy + -4xz + -20y + 80z = -80z + 80z

Combine like terms: -80z + 80z = 0
xy + -4xz + -20y + 80z = 0
