Решите уравнение: 5/6(1/3x-1/5)=3x+3 1/3

5/6 * (1/3x - 1/5) = 3x + 3 1/3;5/6 * 1/3х - 5/6 * 1/5 = 3х + 10/3;5/18х - 1/6 = 3х + 10/3;5/18х - 3х = 10/3 + 1/6;5/18х - 54/18х = 20/6 + 1/6;(5 - 54)18х = (20 + 1)/6;-49/18х = 21/6;х = 21/6 / (-49/18) = 21/6 * (-18/49) = 21 * (-18)/6 * 49) = -9/7;Проверим решение уравнения.5/6 * (1/3х -1/5) = 3х + 3 1/3;5/6 * (1/3 * (-9/7) - 1/5) = 3 * (-9/7) + 10/3;5/6 * (-9/21 - 1/5) = -27/7 + 10/3;5/6 * (-66/105) = -81/21 + 70/21;5 * (-66)/6 * 105 =(-81 + 70)/21;-11/21 = -11/21;уравнение решено правильно.
