The variable a represents Flash's age in months, and the variable p represents Flash's weight in pounds. At how many months did Flash weigh 5 pounds?

months

1 answer

To find out how many months Flash weighed 5 pounds, we can use the equation \( p = a + 3 \).

We know that \( p = 5 \) pounds, so we can set up the equation:

\[ 5 = a + 3 \]

Now, we can solve for \( a \):

  1. Subtract 3 from both sides:

\[ 5 - 3 = a \]

  1. This simplifies to:

\[ a = 2 \]

Therefore, Flash was 2 months old when he weighed 5 pounds.

The answer is:

2 months.
