Answer»

1/ x + 4 - 1/ x-7=11/30; x-7- x+4/( x-7)( x+4)= 11/30; 3/x^2 +4x-7x-7(4) = 11/ 30; 3/x^2 -3x -28 = 11/30; 3(30)=11( x^2-3x-28); 90 = 11x^2-33x-308;; 11x^2 -33x -308-90; 11x^2 -33x -398=0;

1/x+4 -1/x-7=11/30x-7-x-4/(x+4)(x-7)=11/30-11/x^2-3x-28=11/30x^2-3x-28=-30x^2-3x+2=0x^2-2x-x+2=0x(x-2)-(x-2)=0(x-2)(x-1)=0either x-2=0, x=2or x-1=0, x=1
