Answer:

Given equation is,

                 3y(2y - 7) - 3(y - 4)

Also given

                 y = 2

∴  3y(2y - 7) - 3(y - 4) = 3*2(2*2 - 7) - 3(2 - 4)

                                     = 6(4-7)-3(-2)

                                     =(6*-3) +6

                                     =-18+6

                                     =-12

                   Hope it helps you^_^
