Answer:
<h3>x = 27.5</h3>
Step-by-step explanation:
![(x - 3)2 = 49 \\ \frac{(x - 3)2}{2} = \frac{49}{2} \\ x - 3 = 24.5 \\ x - 3 + 3 = 24.5 + 3 \\ x = 27.5 \\](https://tex.z-dn.net/?f=%28x%20-%203%292%20%3D%2049%20%5C%5C%20%20%5Cfrac%7B%28x%20-%203%292%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B49%7D%7B2%7D%20%20%5C%5C%20x%20-%203%20%3D%2024.5%20%5C%5C%20x%20-%203%20%2B%203%20%3D%2024.5%20%2B%203%20%5C%5C%20x%20%3D%2027.5%20%5C%5C%20)
