"I am less than one-half"
This means that the number is less than , or 0.50
"but greater than four tenths"
This means that the number is greater than , or 0.40
"I am a decimal with the digit 2 in my hundredths place"
This means that the number follows the format 0.x2, so we just need to figure out what x is. We know that the number is between 0.40 and 0.50, so the number in this case would be 0.42

Answer:
(4,8) is the answer.
Step-by-step explanation:
To solve by substitution, you need to isolate a variable. The bottom equation already has y isolated, so we can just plug that into the other equation:
Add to both sides in order to get rid of the
on the right side:
Now divide by 4 on both sides to get:
That gives us our x. Now plug in that x into either equation. I will just choose the bottom equation:
Therefore the solution to this problem is (4,8).
