(7-x/x+2)-(1/x-1)=1/3

I know the answer to this, it is 5/2 but can someone please show me the steps to solving this equation? Thx.

2. Hello, clarebear14

1.(7-x/x+2)-(1/x-1)=1/3

mult. both part of eq. by 3*(x+2)(x-1)

2. 3*(7-x)*(x-1) - 3*(x+2)=(x+2)(x-1)

3.-4x^2+20x-25=0

D = 400-400=0

x1=x2=20/8=5/2
