The answer is -8.

x= 9

x = 9

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

If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'

The answer is -8.

x = 9

x= 9

5x = 4x + 9 x = 9

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

If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'

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

If: x+9+5x = 21+2x Then: x = 3

39 = 5x + 9 5x = 39 - 9 5x = 30 x = 30 / 5 x = 6

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

5X + 9 5(3) + 9 15 + 9 = 24 ====

5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
