Answer 1

Answer:

Hey there , the ans comes out to be 21.

Step-by-step explanation:

Given, expression is -

  3y(2y - 7) - 3(y - 4) - 63

Putting y = -2 in the above expression we get

  3x(-2) {2(-2) - 7} - 3(-2 -4) - 63

= -6(-4 - 7) - 3(-6) - 63

= -6x(-11) + 18 -63

= 66 + 18 - 63

= 3 + 18

= 21

Hope this helps you dear.
