Решите уравнение 3х+5 /5+9х-5/4=6+3х+1/ 2

3х + 5/5 + 9х - 5/4 = 6 + 3х + 1/2;3х+ 9х - 3х = 6 + 1/2 - 5/5 + 5/4;9х = 120/20 + 10/20 - 20/20 + 25/20 = (120 + 10 -20 + 25)/20;9х = 135/20;х = 135/20 / 9;х = (135 * 1)/(20 * 9) = 3/4;х = 3/4;Проверим правильно ли решено уравнение.3х + 5/5 + 9х - 5/4 = 6 + 3х + 1/2;3 * 3/4 + 5/5 + 9 * 3/4 - 5/4 = 6 + 3 * 3/4 + 1/2;9/4 + 5/5 + 27/4 - 5/4 = 6 + 9/4 + 1/2;45/20 +20/20 + 135/20 -25/20 = 24/4 + 9/4 + 2/4;(45 +20 +135 -25)/20 = (24 + 9 +2)/4;175/20 = 35/4;35/4 = 35/4;Уравнение решено правильно.
