Question

7(X-19)=133
9(213-2X)=927
1344/(X+26)=32
384:(51-5X)=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=110:2
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=35:5
х=7
