$( 3424 * 1000 - x) - 2300 = 12560\\\\(3424000 - x) - 2300 = 12560\\\\3424000 - x - 2300 = 12560\\\\-x = 12560 + 2300 - 3424000\\\\-x = -3409140\\\\x = 3409140$

$(236000 - y) : 90 = 13106 - 12289\\\\(236000 - y) : 90 = 817\\\\236000 - y = 817 * 90\\\\236000 - y = 73530\\\\-y = 73530 - 236000\\\\-y = -162470\\\\y = 162470$
