Question

daca impartim suma numerelor 279 si 361 la diferenta dintre nr 376 si un alt nr necunoscut obtinem catul 35 si restul 10 aflati nr necunoscut

Answer 1

279+361=640
640:(376-x)=35 r10
35×(376-x)+10=640 |-10
35×(376-x)=630 |:35
376-x=18
x=376-18=358

Answer 2

(279+361)/(376-x)=35 rest 10
a=b*q+r
(279+361)=(376-x)*35+10
640=13160-35x+10
640-10=13160-35x
630=13160-35x
35x=13160-630
35x=12530
x=12530/35
x=358
