Question

x - y + 5z = 2
4x - 3y + 5z =3
3x - 2y + 4z = 1​

Answer 1

Respuesta:

(x= -3) (y=-5) (z=0)

Explicación paso a paso:

x-y+5z = 2 = 5z = 2-x+y

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

3x-2y+4z=1 = 1+4z=1 = z=0

x-y+0= 2 = x=2+y

3x-2y=1 = 3(2+y)-2y = 1 = 6+3y-2y=1 = y=-5

3x-2y=1 = 3x + 10= 1 = 3x= -9 = x= -3
