    Okay ich glaub ich habs verstanden . Okay habe diese aufgabe hier mal gemacht ist alles richtig?

    5x + 2y = 3 / -2y
    3x - 2y = 11 / +2y

    5x=3-2y
    3x=11+2y

    3 - 2y = 11 + 2y /-3
    - 2y = 8 + 2y /-2y
    - 4y = 8 /:(- 4)
    y = -2

    3x = 11 + 2 * -2
    3x = 7 /:3
    x = 2,33

    Also ich rechne so :

    2y - 3x = 9 /-2y
    3x + 7y = 72 /-7y

    -3x = 9 – 2y
    3x = 72 – 7y


    9 – 2y = 72 – 7y /-9
    -2y = 63 – 7y /+7y
    5y = 63 /: 5
    Y = 12,6


    Aber da stimmt das schon nicht in der kontrol lössung steht 9 und 3 aber keine 12,6 habe ich falsch gerechnet?

    Da gibts noch ein Problem der Lehrer gab uns neue aufgaben und auch die lössungen aber nicht den lössungs weg aber egal wie ich rechne die lössung stimmt nicht und er sagte die seien aber alle richtig die er uns gab. Kann mir einer erklären wie die bei der afugabe hier auf die lössung 3 und 9 kommen?


    2y - 3x = 9
    3x + 7y = 72

    Kann mir jemand das auf Deutsch übersetzten ? Wir müssen das bis nächste woche übersetzt haben aber ich sitzte schon seit ner stunde dran und schaf das nicht. Bitte Bitte Bitte Bitte Hilfe....


    Step: 1

    Create a calorie deficit

    „The secret of losing weight can be put in one sentence,“ says diet expert Amanda Ursell, „take in fewer calories than you use up.“ She warns against the present trand for lowcarbohydrate diets, saying , “Any calories that aren´t burned off are stored by your body, wherever they come from.” Altrough a strict diet plan may work, it´s a lot easier to simply make small changes to your existing diet. Try keeping a food diary to work out what you eat regularly. Then start looking for healthier alternatives- for eyample, fruit instead of chocolate or biscuits.

    Step.2

    Get your heart rate up

    Reducing your daily calorie intake will help you lose weight, but the most effective way to get fit is to combine this with regular exercise. Best of all is the kind of activity that raises your heart rate and gets you sweating, such as aerobics, cycling, or running, for a minimum of 45 minutes, three or four times a week. As sports scientist Tony Lycholat points out, “The harder you work, the more energy you use up.” He warns, however, against trying to do too much all at once. “If you are new to execise, build up gradually.”


    Step: 3

    Become an active person

    “Many of us are completely sedentary all week except when we go to the gym,” says Sue Millard. “We think we are being good by exercising, and then can´t understand why we are not getting results.” If you really want to get fit, your gym exercise or runs in the park should be part of a generally active life. Walking or cycling to work is ideal, but every little counts, such as walking up the stairs instead of taking the lift.
