Answer:
Step-by-step explanation:
[tex]\left \{ {{-3x+2y=56} \atop {-5x-2y=24}} \right. <=> \left \{ {-3x+2y=56} \atop -8x=80} \right.< => \left \{ {-3x+2y=56} \atop x= -10} \right. <=> \left \{ {-3.-10+2y=56} \atop x= -10} \right. <=> \left \{ {2y=26} \atop x= -10} \right. <=> \left \{ {y=13} \atop x= -10} \right.[/tex]
