Use the figure at the right. If JK = 9x+28 and NO = 23, what is the value of x?

Figure:
Big triangle.
Top = L
Bottom Left = J
Bottom Right = K
Small triangle in Big one.
Top Left = N
Top Right = O
Bottom = M

Left of triangles = 3 lines between L and N and also between N and J
Bottom of triangles = 1 line between J and M and also between M and K
Right of triangles = 2 lines between L and O and also between O and K
