[tex]x - 33 \frac{21}{25} = 42 \frac{17}{35} \\ x - \frac{33 \times 25 + 21}{25} = \frac{42 \times 35 + 17}{35} \\ x - \frac{846}{25} = \frac{1487}{35} \\ x = \frac{1487}{35} + \frac{846}{25} \\ x = \frac{5 \times 1487 + 7 \times 846}{175} \\ x = \frac{7435 + 5922}{175} \\ x = \frac{13357}{175} = 76 \frac{57}{175} [/tex]
