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.

Solution:

We will use the concepts of algebra to answer the given questions.

The expressions for the given cases are:

(a) 11 added to 2m = 2m + 11
(b) 11 subtracted from 2m = 2m – 11
(c) 5 times y to which 3 is added = 5y + 3
(d) 5 times y from which 3 is subtracted = 5y – 3
(e) y is multiplied by - 8 = - 8y
(f) y is multiplied by -8 and then 5 is added to the result = - 8y + 5
g) y is multiplied by 5 and the result is subtracted from 16 = 16 – 5y
(h) y is multiplied by -5 and the result is added to 16 = - 5y + 16
