Question

:))
By Gauss's elimination method for the equations x + 4y - 2 = -5;
x + y -62 = - 12; 3x - y-z = 4 elimination of x given – 3y - 5z = -7;
-13y + 2z = 19 then value of x, y, z are,​

Answer 1

Step-by-step explanation:

x+4y=-5+2

x+4y=-3(i)

x+y=-12+62

x+y=50(ii)

subtracting (i)from(ii)

x+y=50

x+4y=-3

-3y=53

y =53/-3

x+y=50

x-53/3=50

x=50+53/3

x=150+53/3

x=203/3
