Answer 1

Răspuns:

230·[(2763+m):6:8-7·7]:10:5=460

(2763+m):6:8-49=460:230·10·5

(2763+m):6:8=100+49

2763+m=149·8·6

m=7152-2763

m=4389

Answer 2

Răspuns:

1. 230×[(2763+m):6:8-7×7]:10:5=460

2. 230×[(2763+m):6:8-14]:10=460×5=2300

3. 230×[(2763+m):6:8-14]=2300×10=23000

4. (2763+m):6:8-14=23000:230=100

5. (2763+m):6:8=100+14=114

6. (2763+m):6=114×8=912

7. 2763+m=912×6=5472

8. m=5463-2763

9. m=2709
