Question

Y x (1234+5678)=(198198x199-199199x198)

Answer 1

\(Y\times(1234+5678)=(198198\times199-199199\times198)\)

\(Y\times6912=(198\times1001\times199-199\times1001\times198)\)

\(Y\times6912=0\)

\(Y=0:6912=0\)

Answer 2

Y * ( 1234 + 5678 ) = ( 198198 * 199 - 199199 * 198 )

Y * ( 1234 + 5678 ) = ( 39441402 - 39441402 )

Y * ( 1234 + 5678 ) =                     0

Y *        6912           =            0

Y = ( Vô số )
