Question

x - 1/4= 7/2 - 3/5

x/134 = 9/7 - 5/-11

 

 

Answer 1

\(a,x-\dfrac{1}{4}=\dfrac{35-6}{10}\\ x-\dfrac{1}{4}=\dfrac{29}{10}\\ x=\dfrac{29}{10}+\dfrac{1}{4}\\ x=\dfrac{29.4+10}{40}\\ x=\dfrac{63}{20}\\ b,\dfrac{x}{134}=\dfrac{9.11-5.7}{-77}\\ \dfrac{x}{134}=\dfrac{134}{77}\\ x=\dfrac{134.134}{77}\\ x=\dfrac{17956}{77}\)

Answer 2

x - 1/4 = 7/2 - 3/5

x - 1/4 = 29/10

x = 29/10 + 1/4

x = 63/20

vậy x = 63/20 

 

Answer 3

x-1/4=29/10

x=29/10+1/4

x=63/20
