Answer:

x =  \frac{4}{7}  \\ y =  \frac{ - 2}{7}  \\ z =  \frac{ - 11}{7}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = x  \times (y + z) \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{4}{7}  \times ( \frac{ - 2}{7}  +  \frac{ - 11}{7} ) \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{4}{7}  \times  \frac{( - 2) + ( - 11)}{7}  \\    \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{4}{7}  \times  \frac{ - 13}{7} \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =   \frac{ - 52}{49}
