Question

find the roots of 1/x-4 - 1/x-7=11/30,x is not equal to -4,7

Answer 1

$\frac{1}{x} - 4 - \frac{1}{x} - 7 = \frac{11}{30} \\ \frac{1 - 4x - 1 - 7x}{x} = \frac{11}{30} \\ \frac{ - 11}{x} = \frac{11}{30} \\ \frac{ - 1}{x} = \frac{1}{30} \\ x = - 30$
Hope this answer will help you

Answer 2

1/x-4-1/x=11/30

1-4x-1-7x/x=11/30

-1/x=1/30

X=-30
