Question

3 phần 2 trừ 4 ( 1 phần 4 trừ x) =2 phần 3 trừ 7x 

Answer 1

\(\dfrac{3}{2}-4\left(\dfrac{1}{4}-x\right)=\dfrac{2}{3}-7x\)
\(< =>\dfrac{3}{2}-1+4x=\dfrac{2}{3}-7x\)
\(< =>4x+7x=\dfrac{2}{3}-\dfrac{3}{2}+1\)
\(< =>3x=\dfrac{1}{6}< =>x=\dfrac{1}{18}\)

Answer 2

`3/2 - 4 . (1/4 -x) = 2/7 - 7x`

`3/2 - 1 + 4x = 2/3 - 7x`

`4x+7x = 2/3 - 3/2 +1`

`4x+7x = 4/6 - 9/6 + 6/6`

`4x+7x = 1/6`

`11x=1/6`

`x=1/6 : 11`

`x=1/6 xx 1/11`

`x=1/66`
