Question

va rog dau coroanaaaa!!!!! doar de 3 am nevoie​

Answer 1

Răspuns:

d)34(5x+3y)=58(2x+3y)

170x+102y=116x+174y

170x-116x=174y-102y

54x=72y

y/x=54/72

e)18(7x+2y)=11(4x+7y)

126x+36y=44x+77y

126x-44x=77y-36y

82x=41y

x/y=41/82

c)16(2x-3y)=13(2x+4y)

32x+48y=26x+52y

32x-26x=52y-48y

6x=4y

x/y=4/6

Sper ca este bine!
