1 - n = n - 1
Solve for n in the equation 1 - n = n - 1
Step 1: Group variables:
We need to group our variables -n and n. To do that, we subtract n from both sides
-n + 1 - n = n - 1 - n
Step 2: Cancel n on the right side:
-2n + 1 = -1
Step 3: Group constants:
We need to group our constants 1 and -1. To do that, we subtract 1 from both sides
-2n + 1 - 1 = -1 - 1
Step 4: Cancel 1 on the left side:
-2n = -2
Step 5: Divide each side of the equation by -2
-2n/-2 = -2/-2
n = 1
