2. [936-(8x100+a)]:[10+(35:5+8)]=4 Vă rog urgent​


Răspuns :

[ 936 - ( 8 × 100 + a ) ] : [ 10 + ( 35 : 5 + 8 ) ] = 4

[ 936 - ( 800 + a ) ] : [ 10 + ( 7 + 8 ) ] = 4

[ 936 - ( 800 + a ) ] : ( 10 + 15 ) = 4

[ 936 - ( 800 + a ) ] : 25 = 4

936 - ( 800 + a ) = 4 × 25

936 - ( 800 + a ) = 100

800 + a = 936 - 100

800 + a = 836

a = 836 - 800

a = 36
