Switch up the equation by subtracting.
9-(8*n)=0
Solve : -8n+9 = 0
Subtract 9 from both sides of the equation :
-8n = -9
Multiply both sides of the equation by (-1) : 8n = 9
Divide both sides of the equation by 8:
n = 9/8 = 1.125
Subtract 9 from both sides
9=8n
-9 -9
So the 9 cancels itself out
Then do 8-9=-1
-1n
Then -1/-1 to cancel out the -1 and get the n alone
n=1 or leave it as -1/-1
9=8n
-9 -9
So the 9 cancels itself out
Then do 8-9=-1
-1n
Then -1/-1 to cancel out the -1 and get the n alone
n=1 or leave it as -1/-1
