5. Решите уравнение: a) x + 3,12 = -5,43; б) 1 3/14 - y = 2 3/7; в) 2,6х = -3,51; г) 5/24 x = -1 7/48

a) x + 3,12 = -5,43 x = -5,43 - 3,12 x = -8,55 б) 1 3/14 - y = 2 3/7 17/14 - y = 17/7 y = 17/14 - 17/7 y = 17/14 - 34/14 y = -17/14 y = -1 3/14 в) 2,6х = -3,51 x = -3,51 / 2,6 x = -1,35 г) 5/24 x = -1 7/48 5/24 x = -55/48 x = -55/48 : 5/24 x = -55/48 * 24/5 x = -55/2 * 1/5 x = -11/2 x = -5,5
