1) 3x - 17 = x + 1
2x = 18
x = 9

2) log2 (x - 1) = log2 (2x - 4)
x - 1 = 2x - 4
x = 3

3) x ^ - 2x = 2x + 12
x ^ 2 - 2x = 2x + 12
x ^ 2 - 4x - 12 = 0
(x - 6)(x + 2) = 0
x = 6 or x = -2

4) 2x ^+ 7 = x ^+ 8
2x ^ 2 - x - 1 = 0
(2x + 1)(x - 1) = 0
x = -1/2 or x = 1

5) x^+ 3 = 2x ^+ x + 1
x ^ 2 - x - 2 = 0
(x - 2)(x + 1) = 0
x = 2 or x = -1

6) 2x ^ 2 + 3x = 6x + 2
2x ^ 2 - 3x - 2
(2x + 1)(x - 2) = 0
x = -1/2 or x = 2
