  1. domain D = R \ {3,5/3}

    4/(x-3) - 10/(3x-5) = 1

    4*(3x-5) - 10*(x-3) = (x-3)(3x-5)

    2x + 10 = 3x^2 - 14x + 15

    3x^2 - 16x + 5 = 0

    x=5 or x=1/3


  2. 4(3x-5)-10(x-3)=(x-3)(3x-5)

    12x-20-10x+30=3x^2-5x-9x+15

    3x^2-16x-15=0

    solve x from here


  3. 4/(x - 3) - 10/(3x - 5) = 1

    [x - 3][3x - 5][4/(x - 3) - 10/(3x - 5)] = 1[x - 3][3x - 5]

    4[3x - 5] - 10[x - 3] = [x - 3][3x - 5]

    12x - 20 - 10x + 30 = 3x^2 - 9x - 5x + 15

    3x + 10 = 2x^2 - 14x + 15

    3x^2 - 14x - 2x + 15 - 10 = 0

    3x^2 - 16x + 5 = 0

    3x^2 - x - 15x + 5 = 0

    (3x^2 - x) - (15x - 5) = 0

    x(3x - 1) - 5(3x - 1) = 0

    (3x - 1)(x - 5) = 0

    3x - 1 = 0

    3x = 1

    x = 1/3

    x - 5 = 0

    x = 5

    ∴ x = 1/3 , 5

  4. you have two fractions:

    4 / (x - 3)

    and

    10 / (3x - 5)

    You need a common denominator... Which in this case is

    (x - 3)(3x - 5)

    So... multiply everything by that....

    [(x - 3)(3x - 5)][4 / (x-3)] - [(x - 3)(3x - 5)][10 / (3x - 5)]

    = [(x - 3)(3x - 5)](1)\

    becomes

    4(3x - 5) - 10(x - 3) = (x - 3)(3x - 5)

    12x - 20 - 10x + 30 = 3x^2 - 9x - 5x + 15

    2x + 10 = 3x^2 - 14x + 15

    0 = 3x^2 - 16x + 5

    0 = (3x - 1)(x - 5)

    x = 1/3 and 5

  5. multiply the three terms by (x-3)(3x-5)

    then the first term is: 4(3x-5)

    second: 10(x-3)

    third: (x-3)(3x-5)

    now you have 4(3x-5) - 10(x-3) = (x-3)(3x-5)

    multiply out and solve like usual
