Question

Determine o valor de X em: X/2 + 2X+1/4 = X/8 - 2

Answer 1

x + 2x +1 = x - 2   mmc (2,4,8) = 8
 2      4       8

4x +2.(2x+1)= x - 16
              8

4x +4x +2 = x -16         elimina denominador 8
            8

4x +4x +2 = x -16
4x+4x -x = -16 -2
8x - x = -18
7x = -18
x = -18/7

Answer 2

  x/2+8x+1/4=x-16/8                                                                                                                            4x+16x+2/8=x-2      

4x+16x+2=8x-16

4x+16x-8x=-16-8

12x=-18

x=-18/2

x=-9
