could you please help me solve these for matlab

If the following linear system of equations is given as: 2*x + 4*y -6 = 0 14*x + 16*y - 4*z = 30 12*x + 8*y - 6*z = 20What is the value of x, if it exists? Write: The value of x below, if it exists, or No. if there is no solution, or Infinite, if there is infinite number of solutions Do not write *x ="If the following linear system of equations is given as: 2*x + 4*y -6 = 0 14*x +16*y - 4*z = 30 12*x + 8*y -6*z = 20What is the value of z. if it exists?
