space space space space space space space space open parentheses straight x over 3 plus 1 comma space straight y minus 2 over 3 close parentheses equals open parentheses 5 over 3 comma 1 third close parentheses,  find the values of x and y.

Solution
space space space space space space space space space space space space space space space space open parentheses straight x over 3 plus 1 comma space straight y minus 2 over 3 close parentheses equals open parentheses 5 over 3 comma 1 third close parentheses
rightwards double arrow      space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space straight x over 3 plus 1 equals 5 over 3 space space or space straight x over 3 equals 5 over 3 or space straight x space equals space 2

and           space space space space space space space space space space space space space space space space space space space space space space space space space space space straight y minus 2 over 3 equals 1 third or space straight y equals 1 third plus 2 over 3 equals 3 over 3 or space straight y equals 1
Hence, x =2, y =1
