So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3
The answer is literally-5.7
I feel like it's everything except for choices b and c. I hope this helps, but I would read them again.
There are 0 solutions because the lines are parallel and will never intersect.
