-3(3x + 3y) = -3(10)

***[isuru]*** · Answer

take the second one
                  -9x - 9y = -30
          divide each term by (-3)
                 (-9x)/(-3)  + (-9y)/(-3) = (-30)/(-3)
       where u will get
                 3x + 3y = 10
          which is exactly same as the first one..
        which means  there r infinitely many solutions to this 

hope this will help ya!!
