$\text{a ] }$
$\text{5 , 4 × x = 5 , 4}$
$\text{x = 5 , 4 : 5 , 4}$
$\text{x = 1}$
$\text{vậy x = 1}$

$\text{b ]}$
$\text{9 , 8 × x = 6 , 2 × 9 , 8}$
$\text{9 , 8 × x = 60 , 76}$
$\text{x = 60 , 76 : 9 , 8}$
$\text{x = 6 , 2}$
$\text{vậy x = 6 , 2}$

a, 5,4 × x = 5,4
=> x = 5,4 : 5,4
=> x = 1
———————————————-
b, 9,8 × x = 6,2 × 9,8
=> x = 6,2 × 9,8 : 9,8
=> x = 6,2 × 1
=> x = 6,2
