Answer 1

$(x - \frac{63}{17} ) - \frac{105}{12} = \frac{78}{17} \\ x - \frac{63}{17} - \frac{105}{12} = \frac{78}{17}$

$\frac{63}{17} - \frac{105}{12} = - \frac{252 + 595}{68} = - \frac{847}{68}$

$x - \frac{847}{64} = \frac{78}{17} \\ x = \frac{78}{17} + \frac{847}{16}$

$\frac{78}{17} + \frac{847}{68} = \frac{1159}{68}$

$x = \frac{1159}{68} \\ \\ x = 17 \frac{3}{68}$
