X/3 = Y/5 ... 5X = 3Y ... (1)
Y _ X = 8 ... Y = 8 + X ... (2)
... 5X = 3 ( 8 + X ) = 24 + 3X
2X = 24 ... X = 12
Y _ X = 8 ... Y = 20
-----------
X/3=Y/5 ----> 3Y=5X
Y-X=8 --------> Y=X+8
3(X+8)=5X
3X+24=5X
2X=24 --> X=24/2=12
Y = X+8 =12+8 = 20
---------------
y=8+x
x/3=8+x/5
5x=24+3x
2x=24
x=12;y=20
----------
5x=3y. (1)
y-x=8. (2)
من (2) لدينا:.
y=x+8.
5x=3y
5x=3(x+8)
5x-3x=24
2x=24 ==> x= 24/2 = 12
y=x+8=12+8=20
