Помогите решить уравнения

Answer 1

6) 1g(2-5x)=1

g×(2-5r×cos(0))=1

2g-5gr×cos(0)=1

-5gr×cos(0)=1-2g

            1-2g

r= -   --------------

        5g×cos(0)

        2g-1

r=---------------

     5g×cos(0)

--------------------------------------------------------------

5) 1g(3x-1)=0

g×(3r×cos(0)-1)=0

3gr×cos(0)-g=0

3gr×cos(0)=g

         1

r= --------------

     3cos(0)

     1

r=— ×sec(0)

    3

      sec(0)

r= --------------

           3
