`x` के लिए हल कीजिये:
`1/(x+1)+3/(5x+1)=5/(x+4), x ne -1, -1/5, -4`

Explanation

यहाँ
`1/(x+1) + 3/(5x+1)=5/(x+4)`
`(5x+1+3(x+1))/((x+1)(5x+1))=5/(x+4)`
`rArr (5x+1 +3x+3)(x+4)=5(x+1)(5x+1)`
`rArr (8x+4)(x+4)=5(x+1)(5x+1)`
`rArr 8x^(2)+32x+4x+16 = 5(5x^(2)+x+5x+1)`
`rArr 8x^(2)+36x+16=25x^(2)+30x+5`
`rArr 17x^(2)-6x-11=0`
`rArr 17x^(2)-17x+11x(x-1)=0`
`rArr (x-1)(17x+11)=0`
`rArr x-1=0` या `17x+11=0`
`therefore x=1` या `x=-11/17`
