Question

afla valorile lu N in N÷(8-3)=10 (35+19):N=6 N×(70-63=56

Answer 1

N : ( 8 - 3) = 10
N : 5 = 10
N = 10 × 5
N = 50

Verific:   50 : (8 - 3) = 50 : 5 = 10

(35+19):N=6
54 : N = 6 
N= 54 : 6 
N = 9

 N×(70-63)=56
N×7 = 56
N = 56 : 7 
N = 8

Answer 2

N : ( 8 - 3 ) = 10
N : 5 = 10
N = 10 x 5
N = 50
Verificare: 50 : ( 8 - 3 ) = 10 
                 50 : 5 = 10

( 35 + 19 ) : N = 6
54 : N = 6
N = 54 : 6
N = 9
Verificare: ( 35 + 19 ) : 9 = 6
                  54 : 9 = 6

N x ( 70 - 63 ) = 56
N x 7 = 56
N = 56 : 7
N = 8
Verificare: 8 x ( 70 - 63 ) = 56
                 8 x 7 = 56
