Напишите решение! 6 класс. #1. 53,76: (4,248-1,56х)+3,8=55 #2. 3 1/3-(4 1/5х+х): 5 4/7=8/15

1)53.76:(4.248-1.56х)=55-3.8
53.76:(4.248-1.56х)=51.2
4.248-1.56х=53.76:51.2
4.248-1.56х=1.05
1.56х=4.248-1.05
1.56х=3.198
х=3.198:1.56=2.05

2)3.33-(4.2х+х):5.57=0.53
5.2х:5.57=3.33-0.53
5.2х:5.57=2.8
5.2х=2.8*5.57
5.2х=15.596
х=15.596:5.2=2.99
