Answer 1

Răspuns:

Explicație pas cu pas:

[( 624 + 123 : 3 - a ) : 6 ] × 3 + 254 = 554

[ ( 624 + 41 - a ) : 6 ] × 3 = 554 - 254

( 665 - a ) : 6 = 300 : 3

( 665 - a ) : 6 = 100

665 - a = 100 × 6

665 - a = 600

a = 665 - 600

a = 65

Answer 2

[ ( 624 + 123 : 3 - a ) : 6 ] × 3 + 254 = 554

[ ( 624 + 41 - a ) : 6 ] × 3 + 254 = 554

[ ( 665 - a ) : 6 ] × 3 + 254 = 554

[ ( 665 - a ) : 6 ] × 3 = 554 - 254

[ ( 665 - a ) : 6 ] × 3 = 300

( 665 - a ) : 6 = 300 : 3

( 665 - a ) : 6 = 100

665 - a = 100 × 6

665 - a = 600

a = 665 - 600

a = 65
