100%28-0.71-0.22n%29=100%281.29%2B0.78n%29 Multiply both sides by 100 to clear out the decimals.


-71-22n=129%2B78n Distribute and multiply.


-22n=129%2B78n%2B71 Add 71 to both sides.


-22n-78n=129%2B71 Subtract 78n from both sides.


-100n=129%2B71 Combine like terms on the left side.


-100n=200 Combine like terms on the right side.


n=%28200%29%2F%28-100%29 Divide both sides by -100 to isolate n.


n=-2 Reduce.
