STEP BY STEP EXPLANATION

$\mathsf{ = ( \frac{1}{7} - \frac{1}{8} ) {}^{ - 1} - ( \frac{1}{3} - \frac{1}{4} ) {}^{ - 1}}$

$\mathsf{ = ( \frac{8 - 7}{56} ) {}^{ - 1} - ( \frac{4 - 3}{12} ) {}^{ - 1}}$

$\mathsf{ = ( \frac{1}{56} ) {}^{ - 1} - ( \frac{1}{12} ) {}^{ - 1}}$

$\mathsf{ = 56 - 12}$

$\mathsf{ = 44}$
