    X+y=8
    x-y=2

    Corte os Y e some os 2 X
    2x=10
    x=10 / 2
    x=5

    se a diferena desses dois numero 2 :
    5-2 = 3

    X=5 e y=3

    os dois nmeros so 5 e 3 que resultam em 8

    Oi,

    Resoluo

    Vamos armar o sistema:

    { x + y = 8
    { x — y = 2

    Vou resolver o sistema pelo mtodo da adio,

    2x = 10
    x = 10/2
    x = 5

    Encontramos um nmero, falta o outro, ento,

    x + y = 8
    5 + y = 8
    y = 8 — 5
    y = 3

    S = {( 5 ; 3 )}

    Espero ter ajudado e bons estudos !
