2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5
That all depends.Is it:ln (2x+9) = ln (5x)If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.
x = -5
3(x + 7) > 5x - 13 3x + 21 > 5x - 13 21 + 13 > 5x - 3x 34 > 2x 17 > x The solution set: {x| x < 17}
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
graph the inequality 5x+2y<4
2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5

-5x + 4 > -2x + 31 add 2x and subtract 4 to both sides; -3x > 27 divide by -3 to both sides and change the symbol of the inequality; x < 9
x = -5
3(x + 7) > 5x - 13 3x + 21 > 5x - 13 21 + 13 > 5x - 3x 34 > 2x 17 > x The solution set: {x| x < 17}
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
The given expression has no solution but it can be simplified to: 5x-1045
5x-2x = 3
5x+2x=7x2x + 5x = 7x
5x - 2x = 3x
