Решите уравнение а) 2,136/(1,9-х)=7,12; б)4,2*(0,8+х)=8,82
а)2.136:(1.9-х)=7.12
1.9-х=2.136:7.12
1.9-х=0.3
х=1.9-0.3
х=1.6
б)4.2*(0.8+х)=8.82
3.36+4.2х=8.82
4.2х=8.82-3.36
4.2х=5.46
х=5.46:4.2
х=1.3
А)2.136:(1.9-Х)=7.12 1.9-Х=2.136:7.12 1.9-Х=0.3 Х=1.9-0.3 Х=1.6 Б)4.2*(0.8+Х)=8.82 3.36+4.2Х=8.82 4.2Х=5.46 Х=5.46:4.2 Х=1.3
