How do you mute a particlar string when playing a chord? (the bit in bold)

i would fret the 2 with my index then just rest my middle finger on the X to mute it(just on it but not fretting it)
or
fret the 2 with your index and mute the X with the index aswell (kinda bar it but not enough to fret the X)

Ah right, that simple huh?
Yep, just tried it. Works.

Yeah, that works.

In those particular examples I would use the same finger to fret and mute.

i.e. - if using the index finger on fret 2 string 5, I would lean it back against string 4 to mute it. This is necessary when the other three fingers are already busy. A lot of Zeppelin, AC/DC, and Hendrix type chord material will require this.
