Anika and William are trying to find the x-coordinate of the intersection point of the paths they are walking on. Anika is walking on a path represented by the equation y = 2x + 1 and William is walking on a path represented by the equation y = -3x + 9. Can you help Evelyn figure out the x-coordinate of the point where they will meet?
