Why does the equation 5(3x-4)-6x=3(3x-4) have no solutions?

Because when you add -9x to both sides of the equation and simplify, you get -20 = -12

Because when you add -9x to both sides of the equation and simplify, you get -20 = -20

Because when you subtract -9x from both sides of the equation and simplify, you get -20 = -20

Because when you add -9x to both sides of the equation and simplify, you get 0 = -12
