Question

solve the equation for X given that X + 1 by X - 1 + X - 2 by X + 2 is equal to 3​

Answer 1

Answer:

X=6

Step-by-step explanation:

(X+1/X-1) +(X+2/X-2)=3

X+1/X-1 + X+2/X-2=3

2(X+1)/2(X-1)+ X+2/X-2=3 .....

L.C.M of (X -1)&(X-2)

2X+2/2X-1+X+2/X-2=3

2X+1+X+2/2X-1+X-2=3

3X+3/3X-3=3

X+3/X-3 =3

X+3= 3(X-3)

X+3=3X-9

X-3X=-9-3

-2X=-12

2X=12 ..... [cancelling (-) on both sides]

X=12/2

X=6
