Question

Rezolvati ecuatia in multimea N, efectuind si vereficind: a)x+18=24: b)a+35=20: c)8z=160: d) 5y=18: e)x impartit 12=96: f) t impartit 6=100: g)9x-1=0: h)4x-20=0.

Answer 1

x+18=24  x=24-18=6
a+35=20  a=20--35=-15
8z=160  z=160/8=20
5y=18  y=18/5
x/12=96  x=96*12=1152
t/6=100  t=6*100=600
9x-1=0  9x=1  x=1/9
