Question

please answer question given in Picture​

Answer 1

Answer:

2 or 1

Step-by-step explanation:

1/(x+4)-1/(x-7)=11/30

or, (x-7-x-4)/(x+4)(x-7)=11/30

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

or, -1/(x^2-3x-28)=1/30

or, x^2-3x-28=-30

or, x^2-3x+2=0

or,x^2-2x-x+2=0

or, x(x-2)-1(x-2)=0

or,(x-2)(x-1)=0

or, x=2, x=1
