Question

Solve the following system of equations

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

Answer 1

Answer:

4y +6x-3z please mark me as brain list

Answer 2

The equation of the plane containing the line 2x−5y+z=3;x+y+4z=5 , and parallel to the plane, x+3y+6z=1 , is : (1) 2x+6y+12z=13 (2) x+3y+6z=−7 (3) x+3y+6z=7 (4) 2x+6y+12z=−13
