Answer:
x = 8
Step-by-step explanation:
7x-3x= 32
4x=32
/4 /4
x= 8
To find f(x)-g(x), find (3x-21)-(3x+21)
(3x-21)-(3x+21)
Flip the signs in the second binomial
(3x-21)-3x-21
Combine like terms
3x-3x-21-21
-21-21
-42
The final answer is -42. X is irrelevant because whatever you plug in will always equal -42.
