Answer:
x + 3x + 5 = 101
Explanation:
Consider your problem and think of an equation of each person. We know that Aylen has a certain amount of money, which will be x. Rich though has 5 more than 3 times Aylen.
Aylen: x amount of money
Rich: 5 more than 3 times the amount of money of Aylen.
5 more indicates addition, 3 times indicates multiplication
So then:
Rich: 5 + 3x (where x is the amount of money of Aylen)
Now both of them have $101 together, in other words, if you add up their money they would have $101. So we add their equations:
x + 5 + 3x = 101
Because the operation is addition, we can switch their places and the result will not change so the answer would be:
x + 3x + 5 = 101
