solve krna hai pllzzz. answer de do plzzz

Answer 1

(x-6)(x+7)=(x+3)(x-11)
$(x - 6)(x + 7) = (x + 3)(x - 11) \\ x {}^{2} + 7x - 6x - 42 = x ^{2} - 11x + 3x - 33 \\ x ^{2} + x - 42 = x^{2} - 8x - 33 \\ x ^{2} - x ^{2} - 42 + 33 = - x - 8x \\ - 9 = - 9x \\ cancle - 9 \: to \: - 9 \\ therefore \: \: x = 1$
