If Sophie adds <em>x</em> oz of water, the volume of the new syrup will be (25 + <em>x</em>) oz. The syrup she starts with already contains 0.20 • (25 oz) = 5 oz of sugar, and if she adds water to it, that amount doesn't change.
She wants to end up with a syrup containing 10% sugar, so that the starting 5 oz makes of 10% of the total (25 + <em>x</em>) oz of syrup. So
5 / (25 + <em>x</em>) = 0.10
5 = 0.10 (25 + <em>x</em>)
5 = 2.5 + 0.10<em>x</em>
2.5 = 0.10<em>x</em>
<em>x</em> = 2.5 / 0.10
<em>x</em> = 25 oz
