4x-1/x+1 = 1/4 - 2
4x-1/x+1 = -7/4
4x-1 = (-7/4)(x+1)
4x-1 = -7x/4 -7/4
4x + 7x/4 = -7/4 +1
23x/4 = -3/4
23x = 4(-3/4)
23x = -3
x = -3/23
Comprobando:
4x-1/x+1 +2= 1/4
4(-3/23)-1/(-3/23)+1 +2= 1/4
(-35/23)/(20/23) + 2 = 1/4
-7/4 + 2 = 1/4
1/4 = 1/4
4x-1/x+1 = -7/4
4x-1 = (-7/4)(x+1)
4x-1 = -7x/4 -7/4
4x + 7x/4 = -7/4 +1
23x/4 = -3/4
23x = 4(-3/4)
23x = -3
x = -3/23
Comprobando:
4x-1/x+1 +2= 1/4
4(-3/23)-1/(-3/23)+1 +2= 1/4
(-35/23)/(20/23) + 2 = 1/4
-7/4 + 2 = 1/4
1/4 = 1/4
