You can put this solution on YOUR website! 8/5-(-9n)=7/2n-5
8/5+9n=7n/2-5
9n-7n/2=-5-8/5
(18n-7n)/2=(-25-8)/5
11n/2=-33/5 now cross multiply
55n=-66
n=-66/55
n=-6/5 answer.
PROOF:
8/5-(-9*-6/5)=(7*-6/5)/2-5
8/5-54/5=(-42/5)/2-5
(-46)/5=(-42/5)*1/2-5
-46/5=-42/10-5
-46/5=(-42-50)/10
-46/5=-92/10
-46/5=-46/5
