19x-0,18=19,01    3,2x+5,6+5,8x=17,21 решите уравнения,

Answer 1

19x-0,18=19,01
19х=19,01+0,18
19х=19,19
х=19,19/19
х=1,01


3,2x+5,6+5,8x=17,21
9х+5,6=17,21
9х=17,21-5,6
9х=11,61
х=11,61/9
х=1,29

Answer 2

19х-0,18=19,01
19х=19,01+0,18
19х=19,19 | :19
х=1,01.

3,2х+5,6+5,8х=17,21
3,2х+5,8х=17,21-5,6
