a=2/3

Explanation:

The first step is to multiply out to get rid of the brackets, remembering that multiplying a negative by a negative gives a positive.
2(3-a)-(-2)(a-3)=-(3a-2)

=6-2a-(-2a+6)=-3a+2

=6-2a+2a-6 = -3a+2

Move all the items to the left hand side, remembering to change the sign.

=6-2a+2a-6+3a-2=0

Group the items.

-2a+2a+3a+6-6-2=0

:.3a-2=0

3a=2

a=2/3
