Question

1/6x+2/3x-1/12x=(1-1/2÷2)la a 2-a

Answer 1

amplificãm pe 1/6x cu 2 si pe 2/3x cu 4
2/12x+8/12x-1/12x=(1-1/2×1/2)^2
9/12x=(1-1/4)^2 amplificãm pe 1 cu 4
3/4x=(4/4-1/4)^2
3/4x=3/4^2
3/4x=9/16
x=9/16×4/3
x=3/4

Answer 2

1/6x+2/3x-1/12x=(1-1/2÷2)²

1/6x+2/3x-1/12x = (1-1/2*1/2)²

1/6x+2/3x-1/12x = (1-1/4)²

1/6x+2/3x-1/12x = (3/4)²

1/6x+2/3x-1/12x=9/16

8x+32x-4x=27

36x=27

x = 36/27

x = 3/4
