diferența a doua numere este 131. daca impartim un numar la celalalt obtinem catul 5 si restul.3
Care eeste acel nr??
Va rog!!, ajutati-ma!!

Answer 1

a-b=131
a:b=5r3
a=5b+3
5b+3-b=131
4b=131-3
4b=128
b=128:4
b=32
a-32=131
a=131+32
a=163

Answer 2

$a-b=131 \\ a:b=5 \ r \ 3 \to \boxed{a=5b+3} \\ ****************** \\ 5b+3-b=131 \\ 4b+3=131 \\ 4b=131-3 \\ 4b=128 /:4 \\ b=32 \\ \\ a=5b+3 \\ a=5\cdot32+3 \\ a=163$
