2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8

40

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3

5x + x - 6x + 2x = 2x

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.

2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1

5x+2x-9=40

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3

3x + 2x = 40 5x = 40 x = 8

5x + x - 6x + 2x = 2x

Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer

5x=2x+27 subtract 2x from both sides get get X on only 1 side of the equation. 5x-2x=2x-2x + 27 leaves you with 3x = 27 divide both sides by 3 3x/3 = 27/3 leaves you with x = 9 answer X=9

5X = 2X + 9 subtract 2X from each side 5X - 2X = 2X - 2X + 9 3X = 9 divide each sides integer by 3 (3/3)X = 9/3 X = 3 ------------check in original equation 5(3) = 2(3) + 9 15 = 6 + 9 15 = 15 checks out

If you mean: -3x-5x+1+8x-2x-9 then the result is -2x-8
