Give expressions in the following cases. (a) 11 added to \[2m\] (b) 11 subtracted from \[2m\] (c) 5 times y to which 3 is added (d) 5 times y from which 3 is subtracted (e) \[y\] is multiplied by \[-8\] (f) \[y\] is multiplied by \[-8\] and then 5 is added to the result (g) \[y\] is multiplied by 5 and the result is subtracted from 16 (h) \[y\] is multiplied by \[-5\] and the result is added to 16.                

Answer:

                (a) When 11 is added to \[2m,\] then expression is \[2m+11\]. (b) When 11 is subtracted from \[2m,\] then expression is \[2m-11\]. (c) 5 times of \[y\] is \[5y,\] when 3 added to \[5y,\] then expression is \[5y+3\]. (d) 5 times of \[y\] is \[5y,\] when 3 is subtracted from \[5y,\] then expression is \[5y-3\]. (e) When \[y\] is multiplied by \[-8,\] then expression is \[-8y\]. (f) When \[y\] is multiplied by \[-8,\] then result is \[-8y\] and then 5 is added to it, then expression will be \[-8y+5\]. (g) When \[y\] is multiplied by 5, then result is \[5y\] and then this result is subtracted from 16, then expression will be \[16-5y\]. (h) When \[y\] is multiplied by \[-5,\] then result is \[-5y\] and then this result is added to 16, then expression will be \[-5y+16\].
