Math Question: B2-5=-18

Look at the variable, B, what operations are happening? First multiplication by 2 then subtract 5 (or add -5) . Undo each step first the addtion by adding positive 5, keep balance on both sides so: B2-5+5=-18+5 or B2 = -13. Now undo the multiplication B2/2=-13/2 or B=-13/2 which is also -6.5 or -6 1/2.
