.
3R + 2L = 237     (1)   ("3 yards of ribbon and 2 yards of lace cost $3.37 = 337 cents")
2L - 3R = 103     (2)   ("2 yards of lace cost $1.03 more than 3 yards of ribbon")


Add the equations. You will get


4L = 237 + 103 = 240  ====>  L = 240/4 = 60 cents.


Answer.  One yard of Ribbon costs 60 cents.

         From this point, complete the solution on your own.
