3x + 4y = 14

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

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
