Solve for x:
(5 x+1)(x+3)-8 = 5(x+1)(x+2)
5 x^2 + 15 x + x + 3 - 8 = 5 (x^2 + x + 2 x + 2)
5 x^2 + 16 x - 5 = 5 x^2 + 5 x + 10
5 x^2 - 5 x^2 + 16 x - 5 x -5 -10 = 0
11 x -15 = 0
11 x = 15
x = 15/11
(5 x+1)(x+3)-8 = 5(x+1)(x+2)
5 x^2 + 15 x + x + 3 - 8 = 5 (x^2 + x + 2 x + 2)
5 x^2 + 16 x - 5 = 5 x^2 + 5 x + 10
5 x^2 - 5 x^2 + 16 x - 5 x -5 -10 = 0
11 x -15 = 0
11 x = 15
x = 15/11
