Solution for (3-X)(9-X)=(9-X)(11-X) equation: 


Simplifying
(3 + -1X)(9 + -1X) = (9 + -1X)(11 + -1X)

Multiply (3 + -1X) * (9 + -1X)
(3(9 + -1X) + -1X * (9 + -1X)) = (9 + -1X)(11 + -1X)
((9 * 3 + -1X * 3) + -1X * (9 + -1X)) = (9 + -1X)(11 + -1X)
((27 + -3X) + -1X * (9 + -1X)) = (9 + -1X)(11 + -1X)
(27 + -3X + (9 * -1X + -1X * -1X)) = (9 + -1X)(11 + -1X)
(27 + -3X + (-9X + 1X2)) = (9 + -1X)(11 + -1X)

Combine like terms: -3X + -9X = -12X
(27 + -12X + 1X2) = (9 + -1X)(11 + -1X)

Multiply (9 + -1X) * (11 + -1X)
27 + -12X + 1X2 = (9(11 + -1X) + -1X * (11 + -1X))
27 + -12X + 1X2 = ((11 * 9 + -1X * 9) + -1X * (11 + -1X))
27 + -12X + 1X2 = ((99 + -9X) + -1X * (11 + -1X))
27 + -12X + 1X2 = (99 + -9X + (11 * -1X + -1X * -1X))
27 + -12X + 1X2 = (99 + -9X + (-11X + 1X2))

Combine like terms: -9X + -11X = -20X
27 + -12X + 1X2 = (99 + -20X + 1X2)
