Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?

because if you add 18x to both sides of the equation and simplify, you get −18=−18

because if you add 18 x to both sides of the equation and simplify, you get - 18 = - 18

because if you add 18x to both sides of the equation and simplify, you get 0=−18

because if you add 18 x to both sides of the equation and simplify, you get 0 = - 18

because if you subtract 18x from both sides of the equation and simplify, you get −18=−18

because if you subtract 18 x from both sides of the equation and simplify, you get - 18 = - 18

because if you subtract 18x from both sides of the equation and simplify, you get 0=−18
