Simplifying 15x + 9xy = 21y Solving 15x + 9xy = 21y Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Combine like terms: 21y + -21y = 0 15x + 9xy + -21y = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(5x + 3xy + -7y) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(5x + 3xy + -7y)' equal to zero and attempt to solve: Simplifying 5x + 3xy + -7y = 0 Solving 5x + 3xy + -7y = 0 Move all terms containing x to the left, all other terms to the right. Add '7y' to each side of the equation. 5x + 3xy + -7y + 7y = 0 + 7y Combine like terms: -7y + 7y = 0 5x + 3xy + 0 = 0 + 7y 5x + 3xy = 0 + 7y Remove the zero: 5x + 3xy = 7y 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.
