Answer 1

prima:a+(864-864÷3)÷3=864
a+(864-288)÷3=864
a+576÷3=864
a+192=864
a=864-192
a=672

Sper ca te-am ajutat ,ti lar face pe toate dar trebe' sa plec undeva si nu pot sa le scriu pe toate

Answer 2

a+(864-864÷3)÷3=864
a+(864-288)÷3=864
a+576÷3=864
a+192=864
a=864-192
a=672

a+(515÷5×3-324÷3+3×28)=532
a+(103×3-108+84)=532
a+(309-142)=532
a+167=532
a=532-167
a=365

a-(612÷3+1228÷4-1000÷5×2)=278
a-(204+307-200×2)=278
a-(204+307-400)=278
a-(511-400)=278
a-111=278
a=278+111
a=389

6+[4-(4+4÷4×4-4)+a]÷4=10
6+[4-(4+1×4-4)+a]÷4=10
6+[4-(4+4-4)+a]÷4=10
6+[4-(8-4)+a]÷4=10
6+(4-4+a)÷4=10
6+a÷4=10
a=10-6
a=4÷4
a=1

[136+(42×a×8-905)-27×80]÷5=19
178×a×8-905-2160÷5=19
178×a×8-905-432=19
178×a×8-473=19
178×a×8=19+473
178×a×8=492
178×a=492÷8
178×a=61
a=178÷61
a=2,91803279
