Answer:

Step-by-step explanation:




Replace h(x) first

Now we plug in 3x in f(x)

Now we plug in 15x-4 in g(x)

Answer:
the first number is 3.4 and the second number is 1
Step-by-step explanation:
The computation of the two numbers is shown below:
Let us assume the first number be x
And, the second number be y
Now the equations are
5x + 4y = 21
And,
5x + 9y = 16
Now subtract equation 2 from equation 1
-5y = -5
y = 1
And, the x is
5x + 4 = 21
5x = 17
x = 3.4
Hence, the first number is 3.4 and the second number is 1
the answer to this problem is 12/648
