Question

2x-1 / 2 - 5x-10 / 4 = 3x-1 / 5 - 9(x-2) / 6                                                                                               

Answer 1

$\frac{2x-1}{2}-\frac{5x-10}{4}=\frac{3x-1}{5}-\frac{9(x-2)}{6} \\ \\ 30(2x-1)-15(5x-10)=12(3x-1)-10(x-2) \\ \\ 60x-30-75x+150=36x-12-10x+20 \\ \\ 60x-75x-36x+10x=-12+20+30-150 \\ \\ -41x=-112 \\ \\ x=\frac{-112}{-41} \\ \\ x=\frac{112}{41}$

Answer 2

  Olá,
2x-1 / 2 - 5x-10 / 4 = 3x-1 / 5 - 9(x-2) / 6 
  30.(2x-1)-15(5x-10)=12(3x-1)-10(x-2)
  60x--30-75x+150=36x-12-10x+20
  60x-75x-36x+10x=30-150-12 +20= 
70x-111x=-162+50
    -41x=-112
        x=-112/-41
       x=112/41
