Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x -
) = x -
+
= x
g(f(x)) = g(x +
) = x +
-
= x
Hence f(x) and g(x) are the inverse of each other
Step-by-step explanation:
-3x + 27= -3
-3x = -3-27
-3x = -30
x= 10
Answer:

Answer:
x = 21
Step-by-step explanation:
3x + 18 + 4x + 15 = 180
