Question

n/2+10=3

Answer 1

n/2 + 10 = 3 subtract 10 from each side
- 10 = -10
n/2 = -7 multiply each side by 2
n = -7 * 2

Answer 2

First of all you have to isolate the term n.

To do this you have to remove the denominator of 2.

We can do this by multiplying all terms by two, leaving us with the equation:

n+20=3

Now if we minus both sides of the equation by 20, we will get:

n+20-20=3-20

Which Simplifies to:

n=-17

Answer 3

you didn't multiply each side by 2 only the left side...

Answer 4

right side*

Answer 5

@Henry.Lister should look like
n + 20 = 6

Answer 6

My mistake, I send you my heartiest apologies. n+20=6 is correct. In which case you would be left with -14
