2x+3x = 5x

-5x+3(x+8)=16-2x

2x + 3x + 6 = 5x + 6

3x

3x+56 = 2x+4 3x-2x = 4-56 x = -52

3x+5 = 2x+13 3x-2x = 13-5 x = 8

3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20

-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.

3x - 3 = 2x + 6 3x = 2x + 9 x = 9

2x + 2 = 3x - 57 = x

-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

yes

3x

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

3x - 12 = -2x + 235x = 35 so x = 7

2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2

x = 5 ========== 3x - 9 = -2x + 16 Balance the equation by adding 2x and 9 to both sides: 3x + 2x = 16 + 9 5x = 25 Divide both sides by 5 to get value for x: x = 5

2x+5=3x+1 -x=-4 x=4

3x - 2x + 4 = 0 3x - 2x = -4 x = -4

3x+4 = 2x-3 3x-2x = -3-4 x = -7

if 2x + 3x = 16 then x = 16/5

5x = 3x + 16Taking the 3x to the left side of the equation and changing its sign5x - 3x = 162x = 16Divide by 2x = 8
