Select all of the following expressions that are equivalent to ab - 2 = c
a = c/b -2
b = c + 2/a
ab = c + 2
a - c/2 = b
b - 2/c = a
a = c + 2/b

Option C.

Step-by-step explanation:

The given expression is ab - 2 = c

Option a : a = - 2

                 ab = c - 2b

                Not equivalent to the original expression.

Option b : b = c +

                 ab = ac + 2 ⇒   = c

                Not equivalent

Option c  : ab = c + 2

                  ab - 2 = c

               Equivalent to original expression

Option d : a - = b

                 2a - c = 2b

                Not equivalent

Option e : b - = a

                 bc - 2 = ac ⇒ c (b-a) = 2 ⇒ c =

                 Not equivalent

Option f : a = c +

                ab = bc + 2

                = c

              Not equivalent
