Question

Solve 5n-7p+3n=25p for n

Answer 1

n = 4p

Explanation:

`5n-7p+3n=25p\\8n-7p=25p\\8n=32p\\n=4p`

Answer 2

n=4p

Explanation:

1. group like terms: -7p+5n+3n=25p

2. add similar elements, 5n +3n = 8n --> -7p+8n=25p

3. add 7p to both sides: -7p+8n+7p=25p+7p

4. simplify : 8n=32p

5. divide both sides by 8:
`(8n)/(8)=(32p)/(8)`

6. evaluate: n=4p
