.
Since
g = pairs of gloves purchased
then
12-g = scarfs purchased
.
7g + 5(12-g) = 62
7g + 60-5g = 62
2g + 60 = 62
2g = 2
g = 1 (gloves purchased)

Hi,         

Let x and (12-c) represent the number of gloves and scarves respectively

Note: a scarf cost $5 ($2 less than gloves cost)

Question states

 $7x + $5(12-x) = $62

         2x = $2.00

          x = 1 , the number of gloves. Number of scarves is 11.   (12-1)



CHECKING our Answer

 $7*1 + $5 * 11 = $7 + $55 = $62
