Simplifying 2 + -1x = 4yx + 21 Reorder the terms: 2 + -1x = 21 + 4xy Solving 2 + -1x = 21 + 4xy Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4xy' to each side of the equation. 2 + -1x + -4xy = 21 + 4xy + -4xy Combine like terms: 4xy + -4xy = 0 2 + -1x + -4xy = 21 + 0 2 + -1x + -4xy = 21 Add '-2' to each side of the equation. 2 + -1x + -2 + -4xy = 21 + -2 Reorder the terms: 2 + -2 + -1x + -4xy = 21 + -2 Combine like terms: 2 + -2 = 0 0 + -1x + -4xy = 21 + -2 -1x + -4xy = 21 + -2 Combine like terms: 21 + -2 = 19 -1x + -4xy = 19 Reorder the terms: -19 + -1x + -4xy = 19 + -19 Combine like terms: 19 + -19 = 0 -19 + -1x + -4xy = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(19 + x + 4xy) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(19 + x + 4xy)' equal to zero and attempt to solve: Simplifying 19 + x + 4xy = 0 Solving 19 + x + 4xy = 0 Move all terms containing x to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + x + -19 + 4xy = 0 + -19 Reorder the terms: 19 + -19 + x + 4xy = 0 + -19 Combine like terms: 19 + -19 = 0 0 + x + 4xy = 0 + -19 x + 4xy = 0 + -19 Combine like terms: 0 + -19 = -19 x + 4xy = -19 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
