    -169

    Step-by-step explanation:

    We want to isolate v.

    Method 1: subtract 40 from both sides, obtaining 169 = - v. Then change the sign of both sides, arriving at v = - 169.

    Method 2: Add v to both sides. Then v + 209 = 40.

    Now subtract 209 from both sides, obtaining - 169.
