n x 721 = 72.1 721n = 72.1 (put it in an easier format) n = 0.1 (divide both sides by 721)
0.074 x n = 74 0.074n = 74 (put it in an easier format) n = 1000 (divide both sides by 0.074)
The solution for the first equation n × 721 = 72.1 is n = 0.1 , and for the second equation 0.074 × n = 74 , it is n = 1000 .
