Answer: 
Answer:
A=3, B =3, C = 3
Step-by-step explanation:
9/3 (the letters) = 3 Each
3 - 24 - 3 = -27
2a = 6
6 - 3 + 3 = 6
A, b, c, all equal 3.
Answer:
84
Step-by-step explanation:
Let the first digit = x
Let the second digit =y
x + y = 12
x + 4 = 3*y
===========
From the second equation, we learn that x = 3y - 4
Put that into the first equation.
3y - 4 + y = 12 Combine the left side
4y - 4 = 12 Add 4 to both sides
4y = 16 Divide by 4
4y/4 = 16/4
y = 4
=================
x + 4 = 12
x + 4 - 4 = 12-4
x = 8
So the number is 84
