Question

1. N - 80 = 40 2. 15n = 30 3. N + 284 = 350 4. 6 + 9 = 3 x n 5. N divided by 3 = 6 +1 6. 12 - 8 = n divided by 5 7. 58 x 6 = n - (723 + 327) 8. 4n + 12 = (7 + 9) x 2

Answer 1

HE IS RIGHT

Explanation:

Answer 2

1.
`N=120`

2.
`n=2`

3.
`N=66`

4.
`n=5`

5.
`N=21`

6.
`n=20`

7.
`n=1398`

8.
`n=5`

Explanation:

1.

`N-80=40`

`N=40+80`

`N=120`

2.

`15n=30`

`(15n)/(15)=(30)/(15)`

`n=2`

3.

`N+284=350`

`N=350-284`

`N=66`

4.

`6+9=3* n`

`15=3n`

`(15)/(3)=n`

`n=5`

5.

`(N)/(3)=6+1`

`(N)/(3)=7`

`N=7* 3`

`N=21`

6.

`12-8=(n)/(5)`

`4=(n)/(5)`

`4* 5=n`

`n=20`

7.

`58* 6=n-(723 + 327)`

`348=n-1050`

`348+1050=n`

`1398=n`

8.

`4n+12=(7+9)* 2`

`4n+12=16* 2`

`4n+12=32`

`4n=32-12`

`4n=20`

`n=(20)/(4)`

`n=5`

Therefore, the solutions are 1.
`N=120`

2.
`n=2`

3.
`N=66`

4.
`n=5`

5.
`N=21`

6.
`n=20`

7.
`n=1398`

8.
`n=5`
