1. Answer:

   (1) n=5.75 (2) s=20 (3) n=45

   Step-by-step explanation:

   (1) 8n – 6 = 40

   => 8n = 40 + 6 (6 will go to the other side and the minus sign will change to plus because a sign changes by going to the other side)

   => 8n = 46 (6 will be added to 40 and it will become 46)

   => n = 46 ÷ 8 (simple division but will go to decimal)

   => n = 5.75

   (2) 14s = 280

   => s = 280 ÷ 14 (14 will go to the other side and change its sign from multiplication to division sign)

   => s = 20

   (3) n + 35 = 80

   => n = 80 – 35 (as we saw in the first question that 6 changed it sign from plus to minus so here it will do the vice-versa{just the opposite, will change the plus sign to minus})

   => n = 45
