Question

quien me ayuda porfa​

Answer 1

6y - 4x = 8

2x + y = 12

Despejar y en 1

6y - 4x = 8

6y = 8 + 4x

y = 8/6 + 4x/6

y= 4/3 + 2x/3

Remplazar y en 2

2x + (4/3 + 2x/3) = 12

2x + 4/3 + 2x/3 = 12

2x + 2x/3 = 12 -4/3

2x/1 + 2x/3 = 12/1 - 4/3

8x/3 = 32/3

x= (32/3)/(8/3)

x= 4

Remplazar x=4 en 1

6y-4(4)= 8

6y - 16 = 8

6y = 8 + 16

6y = 24

y = 24/ 6

y=4

y= 3x - 5

y= -2x + 5

Remplazar Y en 2

(-2x - 5)=3x - 5

-5 + 5 = 3x + 2x

0 = 5x

0/5 = x

0=x

Remplazar x=0 en 1

y= -2(0)+5

y= 0 + 5

y= 5
