Answer 1

$\left \{ {{3x-y=10} \atop { \frac{x}{3}+ \frac{y+1}{5} }} \right.$
$\left \{ {{y=3x-10} \atop { \frac{x}{3}+ } \frac{3x-10+1}{5}=0 } \right.$
$\left \{ {{y=3x-10} \atop { \frac{5x+9x-27-15}{15}=0 }} \right.$
$\left \{ {{y=3x-10} \atop {14x-42=0}} \right.$
$\left \{ {{y=3x-10} \atop {14(x-3)=0}} \right.$
$\left \{ {{y=3x-10} \atop {x=3}} \right.$
$\left \{ {{y=3*3-10} \atop {x=3}} \right.$
$\left \{ {{y=-1} \atop {x=3}} \right.$
