Hello,
If they want us to solve for y, let's start by subtracting 6x to both sides. After doing that, the equation is simplified to: 7y = -6x + 8.
To then get "y" by itself, simply divide "y" by 7 to both sides. Simplifying the equation, the equation is now: y = 8 - 6x / 7, letter B.
Hope this helps!
