Question

Resolva o sistema linear:
x+y+z=2
2x+3y+2z=5
2x+3y+(a²-1)=a+1

Answer 1

Explicação passo-a-passo:

Resolva o sistema linear:

x+y+z=2

2x+3y+2z=5

2x+3y+(a²-1)=a+1

-----------------------------------------------------

2x + 2y + 2z = 4

2x + 3y + 2z = 5

y = 1

-----------------------------------------------------

2x + 3 + a^2 - 1 = a + 1

2x = -a^2 + a - 1

x = (-a^2 + a - 1)/2

-----------------------------------------------------

z = 1 - x = (2 + a^2 - a +1)/2

z = (a^2 - a + 3)/2
