Question

Решите уравнение: 1) (x+36)*10 = 1130; 2) 21*x +349 = 832; 3) x:12 + 524 = 1000;

Answer 1

1) (х+36)*10=1130
х=36*10=360
х=1130-360=770
х=770:10=77
х=77
2) х=832-349=483
483:21=23
х=23
3)
х=1000-524=476
476*12
х=5712

Answer 2

1
(х+36)*10=1130
х+36=1130:10
х+36=113
х=113-36
х=77
2
21*х+349=832
21*х=832-349
21*х=483
х=483:21
х=23
3
х:12+524=1000
х:12=1000-524
х:12=476
х=476*12
х=5712
