Step one: 8=16+8n
Step two:isolate the variable by subtracting 16 on both sides (only the 8 and 16 itself)
Step three: this cancels the 16 out which has the equation change to -8=8n
Step four: divide each side by 8
Step five: after dividing, you will get n=-1 because 8 goes into 8 one time and since the top number is a negative, the answer will be a negative.
