Question

Liner equations please help with answer!

Answer 1

n = -
`(4)/(7)`

Explanation:

Given

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

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = -
`(4)/(7)`
