Question

Doimea unui nr este egala cu patrimea altui nr Suma celor doua nr este 48 .Care sunt nr?

Answer 1

x/2=y/4⇒4x=2y⇒x=2y/4  ⇒x=y/2
x+y=48

y/2+y=48
(y+2y)/2=48
3y=48·2
y=96/3
y=32
x=y/2=32/2
x=16

Answer 2

$\frac{x}{4} = \frac{y}{2}$ => 2x=4y =>x=2y
x+y=48 =>2y+y=48 =>3y=48 =>y=16
x=2*16=32
