8² (3x -2) + 5 = 56  I do the exponents first
64 (3x -2) + 5 = 56  I distribute the 64 over the 3x-2
192x - 128 + 5 = 56 I combined liked terms  (-128+5)
192x -123 = 56  I add 123 to both side
192x - 123 +123= 56 + 123  Finally I divide both sides by 192
192x = 179
192       192

x = \(\frac{179}{192}\)
