Question

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

Answer 1

x/2 = y/4  y = 2x
x + y = 48
3x = 48    x = 16  y = 32

Answer 2

1/2x = 1/4y
x+y=48
x=48-y

1/2(48-y) = 1y/4
48-y/2=1y/4
48-y=2 inmultit cu 1y/4
48-y=2y/4
48=2y/4+y
48=2y/4+ 4y/4
48=6y/4
6y=48 inmultit cu 4
6y=192
y=192/6
y=32

x=48-y=48-32=16
