5.5x + 3 = y
7x =y
5.5x + 3 = 7x (-5.5x both sides)
3 = 1.5x (÷1.5 both sides)
X = 2

The red arrows mean the lines are parallel. Since all angles are equal, the larger triangle is similar to the smaller one. Then corresponding sides have the same ratio
(4x -2)/9 = (3x+2)/12
x(4/9 -3/12) = (2/12) +(2/9)
x = (7/18)/(7/36) = 2 . . . . . . . . . corresponding to the 3rd selection
