( \frac{3}{4}  +  \frac{2}{5} ) + x =  \frac{ - 8}{15}  \\  \\ ( \frac{15 + 8}{20} ) +x  =  \frac{ - 8}{15}  \\  \\  \frac{23}{20}  + x =   \frac{ - 8}{15}  \\  \\ x =  \frac{ - 8}{15}  -  \frac{23}{20}  \\  \\ x =  \frac{ - 32 -69 }{60}  \\  \\  x=  \frac{ - 101}{60}  = -1.68

So - 1.68 should be added
