1/2x-5=10 
Add 5 to both sides
1/2x= 15
Divide 1/2 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x=30

To make sure that this is the answer:
1/2(30)=15
Multiply 1/2 by 30
Final Answer: 30=30 Which means that 30 is equal to x.

im guessing youre soling for x so,

1/2x-5=10 ; first step add 5 to both sides

       +5=+5

1/2x=15  ; do get rid of the fraction and get x alone multiply both sides by 2

(2)1/2x=15(2) : the 2 is the recipicol of 1/2 cancelling it out.

x=30
