Mr. Kirkland's Class
The Johnson twins were born eleven years after their older sister. This year, the product of the three siblings' ages is exactly 1181 more than the sum of their ages. How old are the twins?3
So now that we have the equation we can plug it into a graphing calculator and find the x intercept.
Now we see that the X coordinate of the X intercept of the line is 8. Meaning that the age of the two twins is 8 making the sister 19 years old
