Hi, I have questions about solving the two math problems below. I've looked at them both for about two hours. I just completely don't understand them. Thanks so much for taking time to help me, I greatly appreciate it.
Question 1: For all values of a, let < a > be defined as < a > = 4a - 4 . Which of the following equals < 6 > - < 5 >?
B: < 3 >
C: < 4 >
D: < 5 >
E: < 6 >
Question 2: If 5n + p = 3 and 2m - 10n = 2, what is the value of m + p?
The notation < a > = 4a - 4 is means that whenever you see a number surrounded by the angle brackets you should replace it with 4 times the number minus 4. So, for example
For question 2, p appears in the first equation and m appears in the second. Thus use the first equation to find P and the second equation to find m. Finally add p and m.
p can be isolated to the left of the equal sign by subtracting 5n from both sides. Thus
