Answer 1

$left { {{2x-3y=14} atop {7y+5x=10}} right.\\left { {{2x=14+3y} atop {5x+7y=10}} right.\\left { {{x=7+1,5y} atop {5*(7+1,5y)+7y=10}} right.\\left { {{x=7+1,5y} atop {35+7,5y+7y=10}} right.\\left { {{x=7+1,5y} atop {14,5y=-25}} right. \\left { {{y=0,58} atop {x=7+1,5*(-0,58)}} right.\\left { {{y=-0,58} atop {x=7-0,87}} right.\\left { {{y=-0,58} atop {x=6,13}} right. \\Otvet:boxed{(6,13;-0,58)}$
