For this case we have the following expression:
[tex]A + 2b-4c[/tex]
Substituting the given values we have:
[tex]A + 2b-4c = 2 + 2 (3) -4 (6)[/tex]
Rewriting we have:
[tex]A + 2b-4c = 2 + 6-24\\A + 2b-4c = 8-24\\A + 2b-4c = -16[/tex]
Answer:
The value of the expression is given by:
[tex]A + 2b-4c = -16[/tex]
