Question

Solve for n 2/3 (1+n) = -1/2n

Answer 1

- 4/7

Explanation:

Got it right!

Answer 2

`n = -(3)/(7)`

Explanation:

Thinking process:

The equation can be set as follows:

`(2)/(3(1+n)) = -(1)/(2n)`

The lowest common denominator is the product of the two numbers:

3(1+n) and (2n).

Cross-multiplying gives:

`2 (2n) = -1*3(1+n)`

`4n = -3-3n`

solving for n gives:

7n = -3

therefore, n =
`-(3)/(7)`
