  • 1/4 (x-10) =2/3x-6
    x/4 - 10/4 = 2/3x -6
     x-10
    -------   + 6     = 2/3x 
        4
     x-10      24
    -------- +  -----   = 2/3x
         4          4
    x + 14
    ---------     = 2/3x
        4
    x + 14 = 2/3x (4)
    x + 14 = 8/3x
    x = 8/3x - 14
    3x^2 = 8 - 14
    3x^2 = - 6
    x^2 = -6/3
    x^2 = -2
  • 1/4(x-10) = 2/3x-6
    1/4x -10/4 = 2/3x -6
     1/4x-2/3x = 10/4-6
    3/12x - 8/12x = 10/4-24/4
    -5/12x = -14/4 ======> -60x = -168 ====> x = 168/ 60 = 2,8
