Question 678570: x=y-7
x=8y=2

You can put this solution on YOUR website!
Do you mean
x = y-7
x = 8y + 2
????
Rearrange to y = mx+b format
y = x+7
8y = x-2, so y = %281%2F8%29x+-+%281%2F4%29
...
setting the equation equal to each other
x+7 = %281%2F5%29x+-+%281%2F4%29
x - 1%2F5x = %28-1%2F4%29+-+7
%285%2F5%29x+-+%281%2F5%29x+=+%28-1%2F4%29+-+7%284%2F4%29
%284%2F5%29x+=+-%2829%2F4%29
x = %28-29%2F4%29%285%2F4%29
x = -145%2F16
x = -9.0625
Plugging in x to solve for you
y = -9.0625 + 7 = -2.0625
...
(-9.0625, -2.0625) is the solution

If I misinterpreted your x=8y=2, please clarify and I would be happy to help you.
