Answer:
-6
Step-by-step explanation:
Given that,
y = 1
To find the value of the given expression, replace y with 1.
[tex] \rightarrow3y(2y - 7) - 3(y - 4) \\ [/tex]
[tex] \rightarrow3 \times 1(2 \times 1 - 7) - 3(1 - 4)[/tex]
[tex] \rightarrow3(2 - 7) - 3( - 3)[/tex]
[tex] \rightarrow3 \times - 5 + 9 \\ \rightarrow - 15 + 9 \: \: \: \: \: \: \\ \rightarrow - 6 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
