Question

Решите уравнение:
7(х-19)=133
9(213-2х)=927
1344:(х+26)=32
384:(51-5х)=24

Answer 1

7(х-19)=133
х-19=133/7
х-19=19
х=19+19
х=38
9(213-2х)=927
213-2х=927/9
213-2х=103
2х=213-103
2х=110
х=55
1344:(х+26)=32
х+26=1344/32
х+26=42
х=42-26
х=16
384:(51-5х)=24
51-5х=384/24
51-5х=16
5х=51-16
5х=35
х=7
