[tex]\frac{x-1}{2} = x +1=\\ x-1= 2x+2\\\ x=-3[/tex]
[tex]\frac{x-1}{3}= 8\\ x-1=8*3\\ x-1=24\\ x=25\\[/tex]

[tex]\frac{x-1}{2} = x+1 \ \ |\cdot2\\\\x-1 = 2(x+1)\\\\x-1 = 2x + 2\\\\x - 2x = 2 + 1\\\\-x = 3 \ \ /:(-1)\\\\\boxed{x = -3}[/tex]

[tex]\frac{x-1}{3} = 8 \ \ |\cdot3\\\\x-1 = 24\\\\x = 24 + 1\\\\\boxed{x = 25}[/tex]
