Question

Rezolvati in multimea Z ecuatia:
a) x : (-8) = -20
b) y : 38 = 10
c) z : (-19) = -18 cu tot cu verificare

Answer 1

Salut!:)

a) x : ( - 8 ) = - 20

x = - 20 × ( - 8 )

x = 160

Verificare : 160 : ( - 8 ) = - 20 ( A )

b) y : 38 = 10

y = 10 × 38

y = 380

Verificare : 380 : 38 = 10 ( A )

c) z : ( - 19 ) = - 18

z = - 18 × ( - 19 )

z = 342

Verificare : 342 : ( - 19 ) = - 18 ( A )

Bafta!:)
