x(y-4)=

Solution for x(y-4)= equation:

Simplifying
x(y + -4) = 0

Reorder the terms:
x(-4 + y) = 0
(-4 * x + y * x) = 0
(-4x + xy) = 0

Solving
-4x + xy = 0

Solving for variable 'x'.

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

Factor out the Greatest Common Factor (GCF), 'x'.

Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

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

Simplifying
x = 0
Subproblem 2
Set the factor '(-4 + y)' equal to zero and attempt to solve:

Simplifying
-4 + y = 0

Solving
-4 + y = 0

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

Add '4' to each side of the equation.
-4 + 4 + y = 0 + 4

Combine like terms: -4 + 4 = 0
0 + y = 0 + 4
y = 0 + 4

Combine like terms: 0 + 4 = 4
y = 4

Add '-1y' to each side of the equation.
y + -1y = 4 + -1y

Combine like terms: y + -1y = 0
0 = 4 + -1y

Simplifying
0 = 4 + -1y
