Answer:
-75
Step-by-step explanation:
y = 2
Equation --> 3y(2y - 7) - 3(y - 4) - 63
=> 3(2)(2{2} - 7) - [3(2 - 4)] - 63
=> 6(4 - 7) - [3(-2)] - 63
=> 6(-3) - [3(-2)] - 63
=> -18 + 6 - 63 (Minus and minus combine to become plus)
=> -12 - 63 => -75 is the value of 3y(2y - 7) - 3(y - 4) - 63 for y = 2.
