Answer:
              Infinitely many solutions.
Explanation:
               In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).
  Equation no 1:
                             3x + 3y = 10
  Equation no 2:
                            -9x - 9y = -30 
   Now multiply equation no 1 with (3 )
                            3(3x + 3y) = 3(10)
                               9x + 9y = 30             ( equation no 1 )
    Now ADD both the equations
                              9x + 9y = 30
                            <u> -9x - 9y  =-30</u>
                                        0    = 0
