I haven't done algebra for a long time but I believe the approach is to try and put the equation into its simplest form. Obvious place to start is:

(5x542) = 2710

Leaves you with:

2710 + B - 279

B can't be simplified any further as its value is unknown but 2710 and 279 are of the same type, so you can bump the -279 over and take it from the 2710, leaving you with 2431 and 'B' (ie; 2431 + B). It can't be processed any further than that so that's the final answer.

I'm pretty sure we invented computers so we wouldn't ever have to do maths again.
