`1/2 .x - 3/4 . ( x-1)=x`
`⇔1/2 .x - 3/4 . x+3/4=x`
`⇔1/2 .x - 3/4 . x+3/4-x=0`
`⇔-1/4.x+3/4-x=0`
`⇔-5/4.x+3/4=0`
`⇔-5/4.x=-3/4`
`⇔x=-3/4:(-5/4)`
`⇔x=-3/4.(-4/5)`
`⇔x=3/5`
Vậy `x=3/5` là nghiệm của phương trình `1/2 .x - 3/4 . ( x-1)=x`
`1/2 . x - 3/4 . ( x - 1 ) = x`
`1/2 . x - 3/4 . x + 3/4 = x`
`1/2 . x - 3/4 . x + 3/4 - x = 0`
`( 1/2 - 3/4 - 1 ) . x + 3/4 = 0`
`- 5/4 . x = 0 - 3/4`
`- 5/4 . x = - 3/4`
`x = - 3/4 : - 5/4`
`x = 3/5`
Vậy `x = 3/5`
