Question

Stosunek dwóch liczb wynosi 5 : 8 . Ich różnica jest równa 36 . Jakie to liczby ?

Answer 1

X : y = 5 : 8
x-y=36
5y=8x
x=36+y
5y=8(36+y)
5y=288+8y
-3y = 288
y=-96
x=36-96=-60

Answer 2

X/y=5/8
x-y=36
5x=8y
x=36+y
5(36+y)=8y
x=36-y
180+5y=8y
x=36-y
180=8y-5y
x=36-y
180=3y
x=36-y
y=60
sprawdzamy x
x-60=36
x=36+60
x=96

Answer 3

Uklad rownan
x-y=36
5x=8y // : 5

x-y=36
x=1,6y

1,6y-y=36
x=1,6y

0,6y=36
x=1,6y

y= 60
x=1,6 x 60

y= 60
x= 96


Odp: Te liczny to 60 i 96
