Answer:

x = 6

y = -1

Step-by-step explanation:

x = - 6y ----------------------(I)

4x + 10y = 14 ------------------(II)

Substitute x = -6y in equation (II)

4*(-6y) + 10y = 14

-24y + 10y = 14  {Combine like terms}

           -14y = 14   {Divide both sides by 1-4}

               y = 14/-14

y = -1

Now, substitute y = -1 in equation  (I)

x = - 6*(-1)

x = 6
