hope this helps!
Multiplying 4.2 with the value was given in the bracket, then multiply -2 with the values given in the bracket,we get [8.4x - 2.1y - 8.2x + 0.6y]
then we simply the x and y terms, and the answer is [0.2x - 1.5y]

Answer:
B. -2x + 10 is the correct answer
Let me just rewrite the details in a more understandable manner
f(x) = 2x + 7
g(x) = 3x + c
f( g(x) ) = g( f(x) )
Proceeding to the problem, we have to find the value of c by making use of the relationship written by the third equation. The notation f( g(x) ) means that you have to replace x with g(x). So, you would have incorporate one equation to the other, and vice versa. By equating them, we can determine x. Let us start with f( g(x) ) .
f( g(x) ) = 2(3x + c) + 7
f( g(x) ) = 6x + 2c + 7
Next, we do the similar thing to g( f(x) ).
g( f(x) ) = 3(2x+7) + c
g( f(x) ) = 6x + 21 + c
Then, we equate both simplified equations
6x + 2c + 7 = 6x + 21 + c
Let's simplify further by placing c on one side, and the rest on the other side:
2c - c = 6x - 6x + 21 - 7
c = 14
