Each Figure is a Rhombus. Solve for x.

OB = 8x+2

BR = 4x+20

For OB divide 8x by 8 and do the same to the 2 (8x/8) and you just stay with the x an then you divide 2 and 8 and you get 0.25 and that's your answer (x = 0.25)

For BR you divide 4x by 4 and keep the x (4x/4) and then you divide 20 by 4 and get 5 and that's your answer (x = 5)
