Решите уравнение:
1) (х + 9,18): 9 + 102.52 =

ответ:

1) (x + 9,18) : 9 + 102,52 = 250,93;
(x + 9,18) : 9 = 250,93 - 102,52;
(x+ 9,18) : 9 = 148,41;
x + 9,18 = 148,41 9;
х + 9,18 = 1335,69;
x = 1335,69-9,18;
х = 1326,51;

2) (х- 25,92) : 7 + 11,205 = 306,7;
(х - 25,92) : 7 = 306,7 - 11,205;
(х - 25,92) : 7 = 295,495;
х - 25,92 = 295,495 7;
х - 25,92 = 2068,465;
х = 2068,465 + 25,92;
х = 2094,385.
