11x-10y=-47
------------
x-y/3=-9
y-3x/4=3
-----------
2x+y=-3
x-y=-3

Answer 1

Respuesta:

1:

3x=41+4y

3x=41+4y

x={41+4y}{3}

x= 3

41+4y

2:

11x=−47+10y

11x=10y-47

11x=10y−47

x={10y-47}{11}

x=11

10y−47

3:

x=−9+ 3y

x= 3y−9

4:

y− 4/3x =3

−4/3x =3−y

−3x=(3−y)×4

−3x=4(3−y)

x=−3/4(3−y)

5:

2x=−3−y

x=2/−3−y

6:

x=−3+y

x=y−3
