Question

Please help me on thiss

Answer 1

`n=-1.2`

Explanation:

First, solve both sides of the equation:

`3n+5=(1)/(2) (11n+16)`

`3n+5=((1)/(2) )(11n)+((1)/(2) )(16)` (Distribute)

`3n+5=(11)/(2) n+8`

Then, subtract 11/2 n from both sides:

`3n+5-(11)/(2)n=(11)/(2) n+8-(11)/(2) n`

`(-5)/(2)n+5=8`

Now, subtract 5 from both the sides:

`(-5)/(2) +5-5=8-5`

`(-5)/(2) n=3`

For the last step, multiply both the sides by 2 / -5

`((2)/(-5) )*((-5)/(2) )=((2)/(-5) )*(3)`

`n=(-6)/(5)`

Convert it to decimal:

`n=-1.2`

Answer 2

-1.2

Explanation:

3n + 5 = 1/2(11n + 16)

3n + 5 = 5.5n + 8

5 = 2.5n + 8

-3 = 2.5n

-3/2.5 = n

-1.2 = n

Hope this helps!
