( 10a + 16 ) : 16 = 56 + 5 × 2
( 10a + 16 ) : 16 = 56 + 10
( 10a + 16 ) : 16 = 66
10a + 16 = 66 × 16
10a + 16 = 1056
10a = 1056 - 16
10a = 1040
a = 1040 : 10
a = 104

( a × 10 + 16 ) : 16 = 56 + 5 × 2
( a × 10 + 16 ) : 16 = 56 + 10
( a × 10 + 16 ) : 16 = 66
a × 10 + 16 = 66 × 16
a × 10 + 16 = 1056
a × 10 = 1056 - 16
a × 10 = 1040
