Simplifying 7(2x + 2y) = 28xy (2x * 7 + 2y * 7) = 28xy (14x + 14y) = 28xy Solving 14x + 14y = 28xy Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-28xy' to each side of the equation. 14x + -28xy + 14y = 28xy + -28xy Combine like terms: 28xy + -28xy = 0 14x + -28xy + 14y = 0 Add '-14y' to each side of the equation. 14x + -28xy + 14y + -14y = 0 + -14y Combine like terms: 14y + -14y = 0 14x + -28xy + 0 = 0 + -14y 14x + -28xy = 0 + -14y Remove the zero: 14x + -28xy = -14y Combine like terms: -14y + 14y = 0 14x + -28xy + 14y = 0 Factor out the Greatest Common Factor (GCF), '14'. 14(x + -2xy + y) = 0 Ignore the factor 14.Subproblem 1
Set the factor '(x + -2xy + y)' equal to zero and attempt to solve: Simplifying x + -2xy + y = 0 Solving x + -2xy + y = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y' to each side of the equation. x + -2xy + y + -1y = 0 + -1y Combine like terms: y + -1y = 0 x + -2xy + 0 = 0 + -1y x + -2xy = 0 + -1y Remove the zero: x + -2xy = -1y 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.
