Answer:

1

Step-by-step explanation:

 The method I used is elimination.

 x - 2y = 1

-x - 4y = -7         To find y, we need to cancel the x by using it's opposite. This also affects the other numbers in the equation. This makes positive 4 into a negative and positive 7 into a negative.

   Now we are left with,   -2y = 1

                                           -4y = -7

   Add and you get,         -6y = -6

   Divide      -6y/-6     =  -6/-6

      Our answer is, y = 1.
