Question

Solve the system of equations by Adjoint Method;
4x+2y-z-9, x-y+32= -4,2x+y+z=1​

Answer 1

Answer:

Step-by-step explanation:

4x + 2y - z -9 + x-y + 32 = -4 + 2x + y + z = 1

4x + x - 2x + 2y - y - y - z - z = -4 + 9 - 32 = 1

3x - 2z = 5 -32 = 1

3x -2z = - 27 =1

3x - 2z = 1 + 27 = 28

∴ 3x - 2z = 28
