    X+y= 530
    x-y=178

    O que forma um sistema, ento x=178 +y, onde houver o x na equao de soma voc joga esse valor:

    178+y+y=530
    2y=530-178
    y=352/2
    y=176

    e x:

    x+176= 530
    x=530-176
    x=354

    Logo: x=354 e y=176

    Me enganei,desculpe-me correo :
    dar em um sistema de equao :
    x+y = 530
    x — y = 178
    x = 354

    354 + y = 530
    y = 530 — 354
    y = 176
