Question

Ma puteti ajuta va rog
Stiind ca e : f = 4 rest 3 si e+f =123,afla valorile lui e si f

Answer 1

e:f=4rest3=>e=4f+3
f+4f+3=123
5f=120
f=24
e=4*24+3=99

Answer 2

e: f = 4  rest 3 ⇒ e=4*f+3
e+f=123
4 f+3+f=123
5f=123-3
5f=120
f=120:5
f=24
e=4*24+3=96+3
e=99
V: 99:24=4 rest 3
    99+24=123
