x : 2 - 21,67 = 53,32 : 4
x : 2 - 21,67 = 13,33
x : 2 = 13,33 + 21,67
x : 2 = 35
x = 35 * 2
x = 70
Vậy x = 70
`x:2-21,67=53,32:4`
`x:2-21,67=13,33`
`x:2=13,33+21,67`
`x:2=35`
`x=35xx2`
`x=70`
Vậy `x=70`
x : 2 - 21,67 = 53,32 : 4
x : 2 - 21,67 = 13,33
x : 2 = 13,33 + 21,67
x : 2 = 35
x = 35 * 2
x = 70
Vậy x = 70
