    Oi,

    Resoluo:

    x — 2x/ 5 — x/2 = 45

    MMC > 10

    10x/10 — 4x/10 — 5x/10 = 450/10

    10x — 4x — 5x = 450
    x = 450

    Conclumos que o seu salrio R$ 450,00

    X = salrio
    2x/5 = aluguel
    x/2 = alimentao
    R$ 45,00 = restante

    x — 2x x = 45 m.m.c ( 5,2) = 10
    5 2

    Divida o m,m,c 10 pelos denominadores e multiplique a resposta da diviso pelos numeradores.

    x — 2x x = 45
    10 10

    10x — 4x — 5x = 450 Elimine os denominadores
    x = 450

    Resposta: O salrio R$ 450,00
