Математика: Найдите корни уравнений. 7) 36 : (x + 11 4/5) = 1 17/19 8) 44 : (x - 9 3/40) = 1 9/13

Рокистка068 · Answer

7) 36 : (x + 11 4/5) = 1 17/19х + 11 4/5 = 36 : 1 17/19х + 11 4/5 = 36/1 : 36/19х + 11 4/5 = 36/1 * 19/36х + 11 4/5 = 19/1х + 11 4/5 = 19х = 19 - 11 4/5х = 18 5/5 - 11 4/5х = 7 1/5 х=7,28) 44 : (x - 9 3/40) = 1 9/13х - 9 3/40 = 44 : 1 9/13х - 9 3 /40 = 44/1 : 22/13х - 9 3/40 = 44/1 * 13/22х - 9 3/40 = 26/1х - 9 3/40 = 26х = 26 + 9 3/40х = 35 3/40х=35,075...
