Răspuns :
(a×6)-2×(10-5)=44
(a×6)-2×5=44
(a×6)-10=44
a×6=44+10
a×6=54
a=54:6
a=9
(a×6)-2×5=44
(a×6)-10=44
a×6=44+10
a×6=54
a=54:6
a=9
a × 6 - 2 × (10 - 5 ) = 44
a × 6 - 2 × 5 = 44
a × 6 - 10 = 44
a × 6 = 44 + 10
a × 6 = 54
a = 54 : 6
a = 9
a × 6 - 2 × 5 = 44
a × 6 - 10 = 44
a × 6 = 44 + 10
a × 6 = 54
a = 54 : 6
a = 9
