Someone please help me

okay so you did 1-5

Ima do 6-10

(if you didn’t do 1-5) just comment

6)

1/12+1/x=1/6

Multiply all terms by x

you’d get

1x/12+1=1x/6

Now solve that

You’d get 12

7)

1/12+1/x=2

Multipyl each term by x

1x/12+1 = 1x/2

Solve

you’d get

x=2.4

8)

1/8+1/x=1/4

Multiply x

1x/8+1=1x/4

Now solve

x=8

9)

1/10+1/11=1/x

Add 1/10+1/11 and get 21/110=1/x

Solve in proportion

get 5.24

10)

1/6+1/x=1/5

Multiply each by x

1x/6+1=1x/5

Solve

get 30

You’d get 110.21
