Question

2 (3/4 trừ 5x) = 4/5 trừ 3x

Answer 1

`2(3/4-5x)=4/5-3x`

`3/2-10x=4/5-3x`

`10x-3x=3/2-4/5`

`7x=7/10`

`x=7/10:7=1/10`

Answer 2

2(\(\dfrac{3}{4}\)-5x)=\(\dfrac{4}{5}\)-3x
_{^{\(\dfrac{2}{3}\)-10x=\(\dfrac{4}{5}\)-3x
10x-3x=\(\dfrac{3}{2}\)-\(\dfrac{4}{5}\)
7x=\(\dfrac{7}{10}\)
=>x=\(\dfrac{1}{10}\)}}
