You can only add or subtract things that are alike. There are 3 different things here:

The x ,   The y,    The number

Your answer must have these three things

Re-arrange them but make sure you carry the sign in front of the number

   3y-y+5x+3-7x

= 3y-y+ 5x-7x +3

=3y -1y + 5x-7x +3  ( y is short for 1y)

=2y + -2x +3     ( 3-1 gives 2  and 5 -7 gives -2)

=2y -2x +3         (adding a negative is like subtracting)
