If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Simplifying xy + -2y = 4 Solving xy + -2y = 4 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. xy + -2y + 2y = 4 + 2y Combine like terms: -2y + 2y = 0 xy + 0 = 4 + 2y xy = 4 + 2y Divide each side by 'y'. x = 4y^{-1}+ 2 Simplifying x = 4y^{-1}+ 2 Reorder the terms: x = 2 + 4y^{-1}
