Question

3/4 + 5/2 x = 7/2

Answer 1

=>5/2x=7/2-3/4=11/4

=>x=11/4:5/2=11/4x2/5=22/20=11/10

Answer 2

\(\dfrac{3}{4}+\dfrac{5}{2}x=\dfrac{7}{2}\)

\(\Rightarrow\dfrac{5}{2}x=\dfrac{14}{4}-\dfrac{3}{4}\)

\(\Rightarrow\dfrac{5}{2}x=\dfrac{11}{4}\)

\(\Rightarrow x=\dfrac{11}{10}\)

Answer 3

`3/4 + 5/2 x = 7/2`

`=> 5/2x = 7/2 -3/4`

`5/2x = 14/4 -3/4 = 11/4`

`=> x=11/4 : 5/2`

`x=11/4 * 2/5 =11/10`

Vậy `x=11/10`
