    Answer:

    S=32.5

    W=97.5

    Step-by-step explanation:

    S=speed of plane in still air

    W=speed of wind

    —————————————–

    3(S+W)=130

    6(S-W)=130

    —————————————–

    S+W=43.33333…

    S-W=21.66666…

    2S=64.999…

    S=32.5(simplified)

    —————————————–

    32.5+W=130

    W=97.5

    —————————————–
