Question

Metodo de reduccion 1/4x + 1/2y=0,3/5x+1/5y=1

Answer 1

Respuesta:

(x,y)=(-15, 19/2)

Explicación:

1/4x + 1/2y=0,3/5x+1/5y=1

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

0,3/5 .x+1/5y=1}

{x+2y=4

3x+10y=50}

{-3x-6y=-12

3x+10y=50}

4y=38

y=19/2

x+2. 19/2=4

x=-15

(x,y)=(-15, 19/2)

1/4.(-15)+1/2. 19/2= 0,3/5. (-15) + 1/5. 19/2=1

1=1=1

(x,y)= (-15, 19/2
