Answer:

18

Explanation:

36c+9a+63b= collecting 9:

=9*(4c+a+7b)

so it is 4 times the given a+7b+4c which in the definition is equal to 2; so:

=9*(4c+a+7b)=9 * 2=18

FabriBertani · Answer 2 · 2020-06-22T18:15:01+0000

Answer:

18

Explanation:

a + 7b + 4c = 2,

Multiply this equation by 9

9( a + 7b + 4c) = 2*9

9a + 63b +36c = 18

Rearrange the order

36c +9a +63b = 18
