    1. Solve x/6 + 3x/2 = 4/5 – 2x/15. To get credit, you must find the LCD and clear all the denominators.

    x/6 + 3x/2 = 4/5 – 2x/15 Check
    LCD=6 LCD=15 1/6 + 3(1)/2 = 4/5 – 2(1)/15

    6 + 9x = 12-2x 1 + 9 = 12 – 2

    x + 9x = 12 – 2x 10 = 10

    10x = 12 – 2x
    +2x +2x

    12x/12 = 12/12
    x = 1

    LCD:30 : 5x/30+45x/30=24/30-4x/30 : 5x+45x=24-4x : 50x=24-4x : 54x/54=24/54 : [x=0.4]
