a*-2=a divided by 2
5.52=a divided by 2 so
5.52x2=a=11.04

5.52=a*-2

Hi Viktor,

Guest, you had the right idea but you got a bit muddled up.

5.52=a*-2

a*-2 divided by -2 = a
You can do that so long as you do it to the other side as well.

5.52 divided by -2 = a*-2 divided by -2

you can finish it I think.
