Problema Solution

In last night's basketball game,Sally scored 9 less than twice what Lucy scored. The sum of their scores is 27. How many points did Sally and Lucy make individually?

Answer provided by our tutors

Let Lucky scored be x,

So, Sally scored = 9 - 2x

Their sum is 27,

Hence,  x + 9 - 2x = 27

           -x +9 = 27

            x =  -18

Luck scored -18

Sally scored = 9 - 2(-18)

                 = 9 +36

                  = 45
