Question

Afla numarul necunoscut: n : 4-2x96=42 ;3 x 63 + 176 : n =197 ; 744 : 6+n x 3 = 739 : 100 x n - 574 : 2 = 613

Answer 1

n : 4-2x96=42
n:2 - 192 = 42
n :2 = 42+192 
n:2 = 234 
n = 234 x2 
n = 468

3 x 63 + 176 : n =197
189 +176 :n = 197
176:n = 197 - 189
176:n = 8
n=176:8
n= 22

744 : 6+n x 3 = 739
124 +nx3 = 739
nx3 = 739 - 124 
nx3 = 615
n = 615:3
n = 205

100 x n - 574 : 2 = 613
100xn -287 =613
100xn = 613 + 287
100n = 900
n = 900;100
n=9
