Aflati termenul necunoscut
35+a =72
C-36=17
93-m =38
E urgent va dau coronita

Answer 1

35+a =72
a = 72 - 35 
a = 37

C-36=17
c = 17 + 36 
c = 53

93-m =38
m =93 - 38 
m = 55 

Answer 2

Salut,



35 + a = 72 ⇔ a = 72 – 35 ⇔ a = 37 ⇔ S = {37}


c – 36 = 17 ⇔ c = 36 + 17 ⇔ c = 53 ⇔ S = {53}


93 – m = 38 ⇔ m = 93 – 38 ⇔ m = 55 ⇔ S = {55}
