\(x × 3 , 1 + x × 6 , 9 + 5 , 4 = 82 , 08 : 2 , 7\)

\(x × ( 3 , 1 + 6 , 9 ) + 5 , 4 = 30 , 4\)

\(x × 10 = 30 , 4 − 5 , 4\)

\(x × 10 = 25\)

\(x = 25 : 10\)

\(x=2,5\)

Vậy `x=2,5`

\(x × 13 , 27 − x + x × 3 , 73 = 3622 , 5 : 3 , 45 \)

\(x × ( 13 , 27 − 1 + 3 , 73 ) = 1050\)

\(x × 16 = 1050\)

\(x = 1050 : 16\)

\(x = 65 , 625\)

Vậy `x=65,625`
