Simplifying xy + -4x = 0 Reorder the terms: -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'. x(-4 + y) = 0Subproblem 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 = 0Subproblem 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 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
