5,1:(2+2(х-3) -1ц. 1/17 =3
5,1:(2+2(х-3) =3 + 1ц. 1/17
5,1:(2+2(х-3) = 4ц. 1/17
(2+2(х-3) = 5ц. 1/10 : 4ц. 1/17= 51/10 : 69/17
(2+2(х-3) = 289/23 = 12ц.13/23
2(х-3) = 12ц. 13/23 - 2
2(х-3)= 10ц. 13/23
х+3 = 10ц. 13/23 : 2
х+3= 5ц. 13/46
х= 5ц. 13/46 - 3
х= 2ц. 13/46
Пошаговое объяснение:
5,1:(2+2(x-3)-1целая 1/17)=3
2 + 2(x - 3) - 1 1/17 = 5,1 : 3
2 + 2x - 6 - 1 1/17 = 1,7
2x - 5 1/17 = 1,7
2x = 1,7 + 5 1/17
2x = 1 7/10 + 5 1/17
2x = 1 119/170 + 5 10/170
2x = 6 129/170
x = 6 129/170 : 2
x = 1149/170 * 1/2
x = 1149/340
x = 3 129/340
