  1. `+`

    `x + 28 : 7 = 101`

    `x + 28/7 = 101`

    `x = 101 : 28/7`

    `x = 101/4`

    `+`

    `2x – 7 = 53`

    `2x = 53 + 7 = 60`

    `x = 60 : 2 = 30`

    `+`

    `404 : (2x – 9) = 4`

    `2x – 9 = 404 : 4 = 101`

    `2x = 101 + 9 = 110`

    `x = 110 : 2`

    `x = 55`

    `+`

    `119 : (30 – x) = 17`

    `30 – x = 119 : 17`

    `30 – x = 7`

    `x = 30 – 7`

    `x = 23`
