So suppose you have x packets of 6 and y packets of 10. The total number of batteries would be: 6*x + 10*y = 186

In total, you have 25 packets, so the sum of all the packets containing 6 and 10 batteries is: x+y=25

And we don't usually write the asterisk (*) if it's not necessary, so it'd be 6x+10y=186
