6x - 1 = 29 => 6x = 30 => x = 5
Then x2 + x = 25 + 5 = 30

6x - 1 = 29. Add 1 to both sides. 6x = 30. Divide both sides by 6 to find the value of x. x = 5. Plug in to x2+X. (5)2+5 = 25+5 = 30.

4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
3x - 8 = 7 so x = 5
5x + 3 = 6x + 1 Subtract 5x from both sides: 3 = x + 1 Subtract 1 from both sides: 2 = x
x2 + 6x - 2 = 0 x2 + 6x + 9 = 13 (x + 3)2 = 13 x + 3 = ± √13 x = -3 ± √13
