    The answers are 347 and 865. To solve this problem you set up two equations,

    x+y=1212 and x-y=518. You then get the second x by itself by adding y to both sides. You then have x+y=1212 and x=y+518. After this you substitute the x into the first equation and have y+518+y=1212. Then simplify to 2y=694 and y=347

    Now that y=347 you put it in the original equation. Solve and get that x=865
