If 9a+6b+4c=7, what is - 24b-16c-36a

-24b - 16c - 36a = - 28

Step-by-step explanation:

Given the initial equation of 9a + 6b + 4c = 7 and looking at the second equation of - 24b - 16c - 36a, I notice that all of the coefficients of the variables have been multiplied by a factor of - 4. Since all of the factors have been multiplied by the same factor, multiplied the answer to the equation by a - 4 as well will give us the answer to the problem. Since the original answer is 7, multiplying this answer by a factor of - 4: (7) (-4) = - 28.
