Question

a+b+c=297 , a÷b=2r25, a÷c=11r8 . aflati nr.

Answer 1

A+b+c=297 ,
a÷b=2 r25 => a=2b+25
a÷c=11 r8 => a=11c+8

2b+25=11c+8 => 2b=11c+8-25 => 2b=11c-17
a=11c-17+25 => a=11c+8

11c+8+(11c-17):2+c=297 inmultim ecuatia cu 2
22c+16+11c-17+2c=594
35c=594+1
35c=595
c=17
a=11c+8=11*17+8=195
2b=11c-17 => 2b=11*17-17=170 => b=170:2=85

Proba
195+85+17=297
