Heres my take....first combine like terms on the left side of equ......x-1/x+1 = 2/3 Now cross mult..... 3(x-1) = 2(x+1) Distribute.....3x-3 = 2x +2 Subtr.....3x - 2x = 2 + 3 Yields....x = 5
You have set up the first rectangular area = 84...then realize that the sides of new rect. are x+6;and x+14. Set up the equation.. (X+6)(x+14) = 209 be careful when mult. Yu should get.... X=5 Now plug this value into both binomials and the sides are 11
