Question

X supra Y = 3 supra 8
x + y = 44
y - y = ?

Answer 1

(x+y)/(2x+y)=4/5

5(x+y)=4(2x+y)

5x+5y=8x+4y

5x-8x =4y-5y

-3x =-y

3x=y

x/y= 3

Answer 2

presupun ca vrei ori x-y ori y-x fiindca y-y=0
x/y=3/8
8x=3y
x+y=44
3y/8+y=44
3y+8y=352
11y=352
y=352/11=32
x=44-32=12
x-y=12-32=-20
sau 
y-x=32-12=20
