Question

1. Resuelve con el metodo de Igualación o Reducci
4x-3y=5
2x+y=7


2x+2y=1
X+Y=7


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

Answer 1

Respuesta:

Explicación paso a paso:

4 x-3y=5

4x−3y+3y=5+3y

4x=3y+5

4x 4

= 3y+5 /4

x= 3 /4 y+ 5 /4

2x+y=7

2x+y+−y=7+−y

2x=−y+7 .

2x 2

= −y+7 /2

x= −1 /2 y+ 7 /2

2x+2y=1

2x+2y+−2y=1+−2y

2x=−2y+1

2x 2

= −2y+1 /2

x=−y+ 1 /2

X+Y=7

x+y+−y=7+−y

x=−y+7

-1/2x -1/3y =4

−1 /2 x+ −1 /3 y+ 1 /3

y=4+ 1 /3 y −1 /2

x= 1 /3 y+4

−1 /2 x −1 /2

= 1 /3 y+4 −1 /2

x= −2y−24 /3

-2+1/4x = 1/2y

1 /4 x−2+2=

1 /2 y+2 /1 /4

x= 1 /2 y+2

1 /4 x 1 /4

= 1 /2 y+2 /1 /4

x=2y+8

Listo cariño!
