Step-by-step explanation:
=>(3x-1/x+5)-4(x+5/3x-1)=3
=>(3x-1/x+5)-4x-20/3x-1=3
=>[(3x-1)(3x-1)-4x-20(x+5)]/(x+5)(3x-1)=3
=(9x^2-3x-3x+1-4x^2-20x-20x-100)/3x^2-x+15x-5=3
=>5x^2-46x-99=3(3x^2+14x-5)
=>5x^2-46x-99=9x^2+42x-15
=>9x^3-5x^2+42x+46x-15+99=0
=>4x^2+88x+84=0
=>x^2+22x+21=0
=>x^2+21x+x+21=0
=>x(x+21)+1(x+21)=0
=>(x+21)(x+1)=0
=>x= -21 or -1 ans.
