Answer:
10 and 14
Step-by-step explanation:
Let the first number be x and the second number be y, then
x + 18 = 2y → (1)
y + 16 = 3x → (2)
Rearrange (1) expressing x in terms of y by subtracting 18 from both sides
x = 2y - 18 → (3)
Substitute x = 2y - 18 into (2)
y + 16 = 3(2y - 18) ← distribute
y + 16 = 6y - 54 ( subtract 6y from both sides )
- 5y + 16 = - 54 ( subtract 16 from both sides )
- 5y = - 70 ( divide both sides by - 5 )
y = 14
Substitute y = 14 into (3) for corresponding value of x
x = (2 × 14) - 18 = 28 - 18 = 10
The 2 numbers are 10 and 14

Answer:
f(3) - g(2) = 9
Step-by-step explanation:
f(x) - g(x)
f(x) = 7x - 6
g(x) = 3x
7x - 6 - 3x
f(3) - g(2)
7(3) - 6 - 3(2)
21 - 6 - 6 = 15 - 6 = 9
