Answer:
(-2, 4/7)
Explanation:
Ahh the wonderful world of substitution:
x = 7y - 6
x + 7y = 2
So, we need to find what x and y are. Since we know what x is equal to because of the first equation, we can plug that into the second equation:
7y - 6 + 7y = 2
Now let's solve this
14y - 6 = 2
+6 +6
14y = 8
/14 /14
y = 4/7
Now that we know what y is equal to, we can plug this into the equation. I'll choose the first one, since it is much easier:
x = 7(4/7) - 6
x = 4 - 6
x = -2
Therefore, x is equal to -2 and y is equal to 4/7, final answer.
Hope this helps :D
