Question

подалуйста помогите решить два уравнения последние 3-4

Answer 1

3) 15/17-(в-3/17)=6/17

15/17-в+3/17=6/17

18/17-в=6/17

в=18/17-6/17

в=12/17

проверка   15/17-(12/17-3/17)=6/17,  15/17-9/17=6/17,  6/17=6/17

4) 29/43-(м+13/43)=5/43

29/43-м-13/43=5/43

16/43-м=5/43

м=16/43-5/43

м=11/43

проверка   29/43-(11/43+13/43)=5/43,  29/43-24/43=5/43,  5/43=5/43

Answer 2

15/17-(b-3/17)=6/17
15/17-b+3/17=6/17
-b=6/17-15/17-3/17
-b=-12/17
b=12/17

29/43-(m+13/43)=5/43
29/43-m-13/43=5/43
-m=5/43-29/43+13/43
-m=-11/43
m=11/43
