Question 125832
3x+7y=-1 now multiply the other equation by -1 [-7y=6x] now subtract -6x from both sides [-6x-7y=6x-6x. now you have 6x-6x=0 on the right side. now add these two equations.
3x+7y=-1
-6x-7y=0
----------------------------------
-3x=-1
x=-1/-6
x=1/6 answer.
7y=-6*1/6
7y=-1
y=-1/7 answer.
