Full solution

Q. X+2y=−4X+2y=-4
  1. Isolate X: Let's isolate XX on one side of the equation.\newlineX=−2y−4X = -2y - 4
  2. Substitute XX with zz: Now, we substitute XX with zz to find the value of zz.z=−2y−4z = -2y - 4
  3. Unable to Solve: We don't have a value for yy, so we can't solve for zz without more information.
