3b-8b = -5
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
(8a)(8b) = (8c)/(8d); multiply both sides by 8d to obtain (8a)(8b)(8d) = (8c); divide both sides by 8 to obtain (8a)(8b)d = c; divide both sides by (8a)(8b) to obtain d = c/[(8c)(8b)].
7(3) + 8(4) x 2 21 + 32 x 2 43 x 2 86 The final answer is 86.
8b = -65 so b = -8.125
