Question

Lissette's age is 3 years less than twice the age of her sister Francesca. Lissette is 13. How old Francesca and explain.

Answer 1

To answer this, first make a model of the words. They say that Lissette is 3 less than twice the age of Francesca. In math terms that says L = 2*F - 3
Rearrange the equation so that it answers what Francesca's age is.
(L + 3) / 2 = F

Answer 2

Is that the equation?
