Answer 1

Resposta:

a) y - 5 = 9 -> y= 9+5 -> y= 14

b) t+4 = 10 -> t= 10-4 = 6

c) 4a = 16 -> a=16/4 = 4

d) 5u-1 = 19 -> 5u= 20 -> u= 20/5 = 4

e) 6p+3 = 27-2p

8p = 24 -> p= 24/8 = 3

Resolva os problemas:

a) x+12 =26

x= 26-12 -> x = 14

b) x-8= 20 -> x = 20-8 = 12

c) x+15 =29 -> x= 29-15 -> x=14

d) 3x = 36 -> x= 12
