Question

if 8a + 7b + c = 9, what is -6c - 48a - 42b

Answer 1

Answer:

-54

Step-by-step explanation:

8a + 7b + c = 9

We want -6c, but we have c in the equation so multiply by -6

-6(8a + 7b + c) = 9*-6

-48a -42b -6c = -54

Rearranging the equation

-6c - 48a - 42b = -54

Answer 2

The correct answer is -54
