Answer 1

Answer:

The dashed line part of the circuit indicates a balanced Wheatstone bridge so no current will pass through 10 μ F capacitor and we can remove the same ...

Answer 2

Step-by-step explanation:

simplifying

5(n+-2)=10(3n+9)

reorder the terms

5(-2+n)=10(3n+9)

(-2*5+n*5)=10(3n+9)

(-10+5n)=10(3n+9)

reorder the terms

-10 + 5n=10(3n+9)

-10+5n=(9*10+3n*10)

-10+5n=(90+30n)

solving for variable 'n'

move all terms containing n to the left ,all other terms to right

add-30n to each side of the equation

-10+ -25 n=90+30n+ - 30n

combine like terms 30n + -30n =0

-10+ - 25n=90+0

-10+ -25n=90

add 10 to each side of the equation

combine like terms -10 + 10=0

0+ -25n = 90+10

-25n =90+10

combine like terms 90+10=100

-25n=100

divide each side by-25

n=-4

simplifying

n=-4
