#y=120-5x#

Explanation:

Let Sally's weight at any time be #y# and every two months be #x#.

If Sally wanted to lose #5# pounds every two months, then we multiply #5# by #x#.

So if we want to get Sally's weight at any given time, then we must subtract her original weight by how much she has lost every two months.

So, the equation should look like this.

#y=120-5x#

With #120# being her original weight and #5x# being how much weight she has lost.
