Generating Random Numbers within a certain range

I have problems getting random numbers to stay within a certain range. I've tried a few different suggestions, but none of them worked so far. This is the latest one I tried. Using this code generates me numbers between 0-30. But I wanna stay within 50-20.

Suggestions?

 void randomNumbersForEquation() {

        Random randomNumbers = new Random();
        int number1 = randomNumbers.nextInt(51 - 20);
        int number2 = randomNumbers.nextInt(51 - 20);
        textEasyNumber1.setText("" + number1);
        textEasyNumber2.setText("" + number2);

    }

[This](http://stackoverflow.com/questions/363681/generating-random-integers-in-a-specific-range) will help you. – Sangbok Lee Mar 06 '17 at 13:57
... ahem, ... add 20? – Henry Mar 06 '17 at 13:59
@Henry, that doesn't help as all it does is to increase the range from 30-0 to 50-0 again. I don't want that. I want the numbers to be random between 50-20. – Fisnik B. Mar 06 '17 at 14:18
@SangbokLee I've seen some of these examples but I just can't get it to work. Still throws me out the wrong numbers. I was hoping someone would post a proper working code. – Fisnik B. Mar 06 '17 at 14:18
@FisnikB. low: 0+20 = 20, high: 30+20 = 50. Isn't that exactly what you want? – Henry Mar 06 '17 at 14:58
`int number1 = randInt.nextInt(50-20) + 20;` < – Fisnik B. Mar 06 '17 at 15:11
