Point H is the midpoint of side FK. Triangles F G H and K J H are connected at point H. The lengths of sides F H and H K are congruent. The lengths of sides G H and J H are congruent. The length of side F G is 3 x minus 2 and the length of corresponding side J K is 2 x + 4. For the triangles to be congruent by SSS, what must be the value of x? 1 3 6 8
