Answer:
10 and 2
Step-by-step explanation:
Let's call the first number x and he second number y. This will make the equation set up process easier.
Since the sum of the two numbers is 12, you could make the first equation: x+y=12
One number is less than the other so the next equation would be: y=x-8
You can substitute y in the first equation to have x+(x-8)=12
Add the two x's to have 2x and add 8 from both sides (add 8 to both the 12 and 8 to get it to the opposite side of the equal sign to x. This would look like: 2x=20.
Divide 2 by both sides to get 10.
Now you can plug in 2 in place of x in the very first equation again and subtract from both sides to get 2.
