Question

t+m+f=100; t+16= 2x(f+16); m=t-2 aflat f,t si m

Answer 1

t+16=2f+32
t=2f+32-16
t=2f+16

m=t-2
m=2f+16-2
m=2f+14

t+m+f=100
2f+16+2f+14+f=100
5f+30=100
5f=100-30
5f=70
f=70:5
f=15


t=2f+16=2x15+16=30+16=46
m=2f+14=2x15+14=30+14=44

Answer 2

T+m+f=100;
t+16= 2*(f+16)
m=t-2

t+16= 2*(f+16)
t+16= 2f + 32
t=2f+32-16
t= 2f+16
m=t-2
m=2f+16-2
m=2f+14    ⇒  2f+16+2f+14+f=100  ⇒ 5f=100-(16+14) ⇒ 5f=70 ; f= 14


deci:
 
f=14
m=2*14+14 ⇒ m=3*14 ⇒ m=42 ;
m=42
t= 2*14+16 ⇒ t=28+16 ⇒ t=44
t=44

44+42+14=100
