Question

1) 7(x-19)=133
2) 9(213-2x)=927
3) 1344:(x+26)=32
4) 384:(51-5x)=24

Answer 1

1) 7(х-19)=133
х-19=19
х=38

2)9(213-2х)=927
213-2х=103
-2х=-110
х=55

3)1344/(х+26)=32
х+26=42
х=16

4)384/(51-5х)=24
51-5х=16
-5х=-35
х=7

Answer 2

7(38-19)=133. 9(213-2×55)=927. 1344÷(16+26)=32 384÷(51-5×7)=24
