Answer:

solving LHS=(3x = 2)(2x - 5)

                    =6x^2-15x+4x-10

                    =6x^2-11x-10

comparing LHS and RHS

a=6

k=-11

n=-10

so the value of a-n+k=6-(-11)+(-10)

                                   =6+11-10

                                    =16-11

                                      =5
