Answer 1

Respuesta:

x= 3y-4

x= -2+2y

3y-4= -2+2y

3y-2y= 4-2

y= 2

x= -2+2.2

x= 2

y= 1/2x+5

y= (-3-x)3. y= -9-3x

1/2x+5= -9-3x

5+9= -3x-1/2x

14= -7/2x

14:(-7/2)=x

-4=x

y=-9-3(-4)= 3

x= (2-3y)/2

x= (-1+9y)/4

(-1+9y)2=(2-3y)4

-2+18y=8-12y

-2-8= -18y-12y

-10= -30y

-10/-30=y

1/3=y

x= (2-3.1/3)/2

x= 1/2
