Sper ca te am ajutat!

1. a+25=470:10
a+25=47
a=47-25
a=22
2. (b:10)=9x17+6
b:10=153+6
b:10=159
b=10x159
b=1590
3. 100x(c:7+175:5)=6300
c:7+35=6300:100
c:7+35=63

4. (240:10x37) :d=7 rest 6
(24x37):d=7 rest 6
888:d=7 rest 6
d=888:7+6
d= nu știu sigur:( Îmi pare rău dar aici m-am blocat! (îmi dai te rog frumos coronița?)
