Answer: m= -2
7(m+5) = 21
7m + 35 = 21
-35. -35
7m = -14
————-
7. 7
m = -2
We are given the functions:
f(x) = 4 x – 5 --->
1
g(x) = 3 x + 7 --->
2
To find for the value of f(x) + g(x), all we have to do is
to add equations 1 and 2:
f(x) + g(x) = 4 x – 5 + 3 x + 7
f(x) + g(x) = 7 x + 2 = y
In this case, for any real number value assign to x, we get
a real number value of y. This is because the function is linear.
Therefore the domain of the function is all real numbers.

The correct anwer is -21 and how i got that is by taking -7*300 to get -21 as my answer let me know if it helped any...
