Question

find z by using determinant method X + 2y = -3z +6 ,2x + z = 7 - 4y , 9z + 2y = 14 -3x​
I will mark as brainleast if u will give me required answer.

Answer 1

Answer:

let the value of x,y,z is z.

x+2y+2x+z+9z+2y = -3z+6+7-4y+14-3x

3x+4y+10z = -3z+27-4y-3x

3x+3x+4y+4y+10z+3z = 27

6x+8y+13z = 27

let the value of x,y and z be z.

6z+8z+13z = 27

27z = 27

z = 1
