Solve the system by substitution: {x-7y=(-46) <1st equation>; 2x-6y=(-44)<2nd equation>

I have tried reducing the 2nd equation to have it equal to x to plug into 1st equation, which gave me 3y-22-7y=(-46) after plugging. What I got for y was (-6), I then plugged (-6) into 2nd equation in original form and got (-40) for x. My answer of (-40,-6) was incorrect, please tell me what I have done wrong.
