2x = 3y
2 y = x + 5
2x = 3y
2y-x = 5 / x2
2x = 3y
4y -2x = 10
4y - 3y = 10
y = 10
lis wazy 10 kg
3y = 2x
3 x 10 = 2x
30 = 2x /:2
x = 15 kg
Borsuk wazy 15 kg
lis - y
obliczyć to można układem równań
2x = 3y
2 y = x + 5
2 x = 3 y
2 y - x = 5 / x2
2 x = 3 y
4 y - 2 x = 10
4 y - 3 y = 10
y = 10
lis = 10 kg
3y = 2x
3 x 10 = 2x
30 = 2x /:2
x = 15 kg
Borsuk = 15 kg

{ 2x=3y
{ 2y=x+5
2x=3(½x + 2½)
2x=1½x + 7½
½x=7½ /÷½
x=15
y=½x+2½
y=7½+2½
y=10
