Answer: 
Newborn = 18 inches
adult boa = 9 * 18 + 2 = 164 inches
Since all the information is given, then merely put the necessary facts in order.
Had the length of the newborn been unknown, it would have been represented by x.
9x + 2 = 164
9x = 164 - 2
9x = 162
9x/9 = 162/9
x = 18
Answer:
Solving with an equality is just simply the same as solving any algebra equations. If you were given a fraction, then just multiply both sides.
Example:
4 +
> 14
Subtract 4 on both sides:
4 - 4 +
> 14 - 4
> 10
Now <em>multiply both sides by 2</em>:
× 2 > 10 × 2
x > 20
I answered this using trial and error, so let me know if you need workings, but I got the dimensions as 18 inches and 13 inches.
I hope this helps!
