Answer:

Step-by-step explanation:

x + 3 y = 1 ----------------(I)

-3x - 3y = -15 -------------(II)

Add the equations and y will be eliminated and we can find the value of x

(I)     x + 3y = 1

(II)   -3x -3y = - 15   {Now add}

      -2x         = - 14

                 x = -14/-2

x = 7

Plugin x =7 in equation (I)

7 + 3y = 1

    3y = 1 - 7

     3y = -6

       y = -6/3

y = -2
