Question

1,5 x x - 25% = x tìm x

Answer 1

`1,5 xx x -25% = x`

`1,5 xx x - 1/4 - x =0`

`(1,5 - 1) xx x = 1/4`

`0,5 x =1/4`

`1/2 x =1/4`

`x = 1/4 : 1/2`

`x=1/2`

Answer 2

Ta có: \(1.5\cdot x-25\%=x\)

\(\Leftrightarrow1.5x-x=\dfrac{1}{4}\)

\(\Leftrightarrow x\cdot\dfrac{1}{2}=\dfrac{1}{4}\)

hay \(x=\dfrac{1}{2}\)
