Salut!

Răspuns: - 30 ✅

✏ 2 x [ 12 x 10 : 6 - ( 200 - 5 x 4 ) : 9 + 15 x 4 - a ] = 60

2 x [ 120 : 6 - ( 200 - 20 ) : 9 + 60 - a ] = 60

2 x ( 20 - 180 : 9 + 60 - a ) = 60

2 x ( 20 - 20 + 60 - a ) = 60

2 x ( 0 + 60 - a ) = 60

2 x ( 60 - a ) = 60

60 - a = 60 : 2

60 - a = 30

a = 30 - 60

a = -30 ✅
