Jamie has 31 days left until her 13th birthday. This is one day more than three times as many days as Lou has until his 13th Birthday. Use b to represent how many days until Lou's 13th Birthday.

Answer 1

To find the number of days until Lou's 13th birthday, we can start by setting up an equation based on the given information:

31 = 3b + 1

Now, we can solve for b by first subtracting 1 from both sides:

30 = 3b

Next, we can divide both sides by 3 to solve for b:

b = 10

Therefore, Lou has 10 days left until his 13th birthday.
