    X^4/12 + 6X^3/7 + 3X^2/8 + 5 7X^4/12
    + 5X^2/8 - 5.

    LCD = 168.

    (14X^4 + 144X^3 + 63X^2 - 98X^4 + 105X^2) / 168,
    Combine like-terms:
    (-84X^4 + 144X^3 + 168X^2) / 168,

    Factor out 12X^2:
    12X^2(-7X^2 + 12X + 14) / 168,
    Divide numerator and denominator by 12 and get:
    X^2(-7X^2 + 12X + 14) / 14.

    1/3 - 5/6 = 1/X SOLVE 1/3 - 5/6 = 1/X Let's remove the denominators by multiplying by 12X 12X*(1/3) - 12X*(5/6) = 12X*(1/X) Clear the fractions. 4X - 10X = 12 -6X=12 multipy by -1 6X=-12 Divide both sides by 6 6X/6 = -12/6 X = -2 Check …

    5x -3 = 11 + 12x combine like figures add 3 to both sides to remove the 3 5x= 14+ 12x Now I get confused. If I remove the 12x I have to subtract 12x from 5x which gives me an answer of -7x=14 would the correct answer thus be x= -2?
