20x^2 + 27x + 9 = 0
20x^2 + 15x +12x + 9 = 0
5x(4x + 3) + 3(4x + 3) = 0
(5x + 3)(4x + 3) = 0
So either (5x + 3) = 0 which yields x = -3/5 or (4x + 3) = 0 which yields x = -3/4

7x+2-2=16-27x = 147x/7 = 14/7x = 2
2275.91 = 28xx = 81.2825
Is the same as: 27x+1 = 3 Deduct 1 from both sides: 27x+1-1 = 3-1 27x = 2 Divide both sides by 27: x = 2/27
