Question

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

 

Answer 1

`2(3/2 - x) - 1/3 = 7x - 1/4`

`-> 8/3 - 2x = 7x - 1/4`

`-> 8/3 + 1/4 = 9x`

`-> 35/12 = 9x`

`-> x  = 35/108`

Answer 2

\(2\left(\dfrac{3}{2}-x\right)-\dfrac{1}{3}=7x-\dfrac{1}{4}\)
\(< =>3-2x-\dfrac{1}{3}=7x-\dfrac{1}{4}< =>\dfrac{35}{12}=9x< =>x=\dfrac{35}{108}\)
 

Answer 3

\(2\left(\dfrac{3}{2}-x\right)-\dfrac{1}{3}=7x-\dfrac{1}{4}\\ 3-2x-\dfrac{1}{3}-7x+\dfrac{1}{4}=0\\ -9x+\dfrac{35}{12}=0\\ -9x=-\dfrac{35}{12}\\ x=\dfrac{35}{108}\)
