Answer:

n = - \frac{4}{7}

Step-by-step explanation:

Given

\frac{2}{3} (1 + n) = - \frac{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 = - \frac{4}{7}
