Question

Cum se poate rezolva ex:94326-123×8:[848:4-a×100+5×2)]+838149:3=373217​

Answer 1

94326-123×8:[848:4-a×100+5×2)]+838149:3=373217

Facem calculele si il aflam pe a :

94326-984: [212-(a×100+10)]+279383=373217

94326-984: [212-(a×100+10)] =373217-279383

94326-984: [212-(a×100+10)]=93834

984: [212-(a×100+10)]=94326-93834

984: [212-(a×100+10)]=492

212-(a×100+10)=984:492

212-(a×100+10)=2

a×100+10=212-2

a×100+10=210

a×100=210-10

a×100=200

a=200:100

a=2

Answer 2

94326 - 123 × 8 : ( 848 : 4 - a × 100 + 5 × 2 ) + 838149 : 3 = 373217

94326 - 984 : ( 212 - a × 100 + 10 ) + 279383 = 373217

94326 - 984 : ( 212 - a × 100 + 10 ) = 373217 - 279383

94326 - 984 : ( 212 - a × 100 + 10 ) = 93834

984 : ( 212 - a × 100 + 10 ) = 94326 - 93834

984 : ( 212 - a × 100 + 10 ) = 492

212 - a × 100 + 10 = 984 : 492

212 - a × 100 + 10 = 2

212 - a × 100 = 2 - 10

212 - a × 100 = - 8

a × 100 = 212 - ( - 8 )

a × 100 = 220

a = 220 : 100

a = 2, 2
