5/6 + 1/3
1/3 = 2/6
5/6 + 2/6
=7/6 or 1 1/6
Step 1. Factor out the common term 2
n - 2 = 2(5n + 2)/2
Step 2. Cancel 2
n - 2 = 5n + 2
Step 3. Subtract n from both sides
-2 = 5n + 2 - n
Step 4. Simplify 5n + 2 - n to 4n + 2
-2 = 4n + 2
Step 5. Subtract 2 from both sides
-2 - 2 = 4n
Step 6. Simplify -2 - 2 to -4
-4 = 4n
Step 7. Divide both sides by 4
-1 = n
Step 8. Switch sides
n = -1
