Start from

\dfrac{|10-7|}{4} - \dfrac{|-15+8|}{6}

Perform the additions inside the absolute values:

\dfrac{|3|}{4} - \dfrac{|-7|}{6}

The absolute value does nothing to positive numbers, while it switches the sign of negative numbers, so |3|=3 and |-7|=7:

\dfrac{3}{4} - \dfrac{7}{6}

Transform both fractions so that they have the same denominator:

\dfrac{9}{12} - \dfrac{14}{12} = \dfrac{-5}{12}
