Question

afla valoarea necunoscutei 'x'
x:5=109 rest 3
x:9=72 rest 6
x:10=36 rest 4

Answer 1

$x:5=109r3 \\ x=5*109+3=548 \\ x:9=72r6 \\ x=9*72+6=654 \\ x:10=36r4 \\ x=10*36+4=364$

Answer 2

1) x:5=109 rest 3
Folosim teorema impartirii cu rest si avem
   x=5*109+3=545+4
   x=548

2)x:9=72 rest 6
   x=9*72+6=648+6
   x=654

3)x:10=36 rest 4
  x=360+4
  x=364
