3/x -13/x-11

OpenStudy (anonymous):

3/x -13/x-11=0 so 1/x(3-13)=11 1/x* -10=11 1/x=-11/10 x=-10/11

ok see here: $3/x - 13/x - 11=0$ $\text{let us take common 1/x , ok}$ $1/x(3-13)-11=0$ $1/x(-10)-11=0$ $-10/x-11=0$ $-10/x=11$ $\text{divide both sides by -10}$ $1/x=11/-10$ $1/x=-11/10$ $\text{multiplying both sides by x}$ $1=-11/10x$ $\text{divide both sides by -11/10}$ $x=-10/11$

other way maybe faster way 1st take the LCD which is x $3/x -13/x - 11 = 0$ $3 - 13 -11x = 0 ; 10 -11x = 0 ; x = -10/11$

OpenStudy (anonymous):

3/x -13/x have same denominator 3/x -13/x = (3-13/x = -10/x 3/x -13/x -11 =0 -10/x -11 = 0 Add 10x on both sides -11 = 10x Divide by 10 -11/10 = x
