Well, my question is the following: I have a `.txt`

file that consists of the following data:

```
r&=3&a&=3&b&=4&c&=10\
r&=3&a&=8&b&=15&c&=120\
r&=3&a&=20&b&=55&c&=1540\
r&=4&a&=34&b&=119&c&=7140\
r&=5&a&=24&b&=70&c&=4900\
r&=5&a&=11&b&=22&c&=946\
r&=9&a&=10&b&=19&c&=1045\
r&=10&a&=18&b&=45&c&=5985\
r&=10&a&=49785&b&=6413415&c&=123395663059845\
r&=13&a&=91839&b&=16068720&c&=774611255177760\
...
...
...
```

Now, I want to use Mathematica to make a `ListPlot()`

of my data with the points $(r,a)$.

Let’s give an example. In order to input my file I can use:

```
In(1):=Import("name of the file.txt", "Data")
Out(1)={{r&=3&a&=3&b&=4&c&=10\},{r&=3&a&=8&b&=15&c&=120\},
{r&=3&a&=20&b&=55&c&=1540\},{r&=4&a&=34&b&=119&c&=7140\},
{r&=5&a&=24&b&=70&c&=4900\},{r&=5&a&=11&b&=22&c&=946\},
{r&=9&a&=10&b&=19&c&=1045\},{r&=10&a&=18&b&=45&c&=5985\}
```

Now, I want Mathematica to plot the following points (using `ListPlot()`

):

$$(3,3),(3,8),(3,20),(4,34),(5,24),(5,11),(9,10),(10,18)$$

In reality my data is way bigger. But this small example demonstrates the code I am looking for. Thank you so so much for your help and time.
