By what is given,
$4{N}_{1}-3{N}_{2}=0...\left(1\right),\phantom{\rule{1ex}{0ex}}\text{and}\phantom{\rule{1ex}{0ex}},{N}_{1}+{N}_{2}=-7...\left(2\right).$
$\left(2\right)⇒3\left({N}_{1}+{N}_{2}\right)=-21,i.e.,3{N}_{1}+3{N}_{2}=-21...\left(2\prime \right).$
$\left(1\right)+\left(2\prime \right)⇒4{N}_{1}+3{N}_{1}=0+\left(-21\right),$
$⇒7{N}_{1}=-21⇒{N}_{1}=-\frac{21}{7}=-3,\phantom{\rule{1ex}{0ex}}\text{&, by (2), then,}\phantom{\rule{1ex}{0ex}}{N}_{2}=-4.$
