see below
Explanation:
1 Large frame costs = 17 $
Therefore, x large frames costs = 17x $
{where x is the number of large frames she bought}
1 Small frame costs = 5 $
Therefore, x Small frames costs = 5y $
{where y is the number of small frames she bought}
By the given condition :
&
Solve these equations simultaneously, from second equation we get x = 18 - y
Put this in equation 1
Put y = 11 in eq x = 18 - y
So the woman bought 7 large frames and 11 small frames.
