<span>–(2n + 4) + 6 = –9 + 4(2n + 1)
-2n - 4 + 6 = - 9 + 4*2n + 4*1
</span>
<span>-2n - 4 + 6 = - 9 + 8n + 4
Take all the n's to one side and numbers to the other side. Sign changes to + or - when equality sign is crossed to other side of equation.
</span>
<span>-2n - 8n = - 9 + 4 + 4 -6
-10n = -7
n = -7/-10
n = 7/10 or 0.7
