deci....am ajuns la acest punct la problema x-1 supra 3/2 = 7/3 -1 supra 3/2...trebuie sa il aflu pe x...deci...ma abonez..dau coroana etc etc

Answer 1

x-1/1 :3/2=7/3- 1/1:3/2
x-1/1×2/3=7/3-1/1×2/3
x-1×2/3=7/3-2/3
x-1×2/3=5/3
x-1×2=5/3×3/1
x-1×2=15/3
x-1×2=5
x-1=5/2
x=5/2+1/1
x=5+2×1 totul supra/2
x=7/2

x-1/1+ 1/2=7/3-1/3-3/2
x-1/1+1/2=2×7-2×1-3×3 totul supra /6
x-1/+1/2=14-2-9 totul supra/6
x-1/1+1/2=3/6
x-1×2+1totulsupra/2=3/6
x-1×2+1=3/6×2/1
x-1×2+1=6/6
x-1+2=1+1
x-1+2=2
x-1=2-2
x-1=1
x=1+1
x=2
