Question

3x + 4y = 14
– 3x – 4y = -14 solve using Gauss-jordan elimination​

Answer 1

Answer:

Step-by-step explanation:

Matrix'is determinat:

X1    Y1

X2   Y2

D=(X1*Y2) - (X2*Y1)

D=(3X-4) -  (-3*4)

D=0

Determinant of X

I 1       Y1

I 2      Y2

DX=( I 1 *Y2) - ( I 2*Y1)

DX= (14* -4) - (-14*4)

DX=0

Determinant of Y

X1    I 1

X2   I 2

DY= (X1 * I2) - (X2* I1)

DY=(3X-14) - (-3*14)

DY=0

The result of the variables are solved by:

X=DX/D....            Y=DY/D

X=0/0                  Y=0/0

X=NaN                 Y=NaN
