The answer would be x + x + 2 = 72. Combine like terms so that 2x + 2 = 72. 2x = 70 and x = 35.

Step-by-step explanation:
Length of aluminium strip = ![7 \frac{1}{7} cm](https://tex.z-dn.net/?f=7%20%5Cfrac%7B1%7D%7B7%7D%20cm)
Length of aluminium strip =![\frac{50}{7} cm](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B7%7D%20cm)
Breadth of aluminium strip =![1 \frac{3}{7} cm](https://tex.z-dn.net/?f=1%20%5Cfrac%7B3%7D%7B7%7D%20cm)
Breadth of aluminium strip =![\frac{10}{7} cm](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7D%20cm)
Area of strip = ![Length \times Breadth = \frac{50}{7} \times \frac{10}{7} =\frac{500}{49}](https://tex.z-dn.net/?f=Length%20%5Ctimes%20Breadth%20%3D%20%20%5Cfrac%7B50%7D%7B7%7D%20%5Ctimes%20%20%5Cfrac%7B10%7D%7B7%7D%20%3D%5Cfrac%7B500%7D%7B49%7D)
Diameter of circle = ![1 \frac{3}{7} cm](https://tex.z-dn.net/?f=1%20%5Cfrac%7B3%7D%7B7%7D%20cm)
Diameter of circle = ![\frac{10}{7} cm](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7D%20cm)
Radius of circle =![\frac{10}{ 7 \times 2}=\frac{10}{14} cm](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B%207%20%5Ctimes%202%7D%3D%5Cfrac%7B10%7D%7B14%7D%20cm)
Area of circle =![\pi r^2 = \frac{22}{7} \times (\frac{10}{14})^2=\frac{550}{343} cm^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%3D%20%5Cfrac%7B22%7D%7B7%7D%20%5Ctimes%20%28%5Cfrac%7B10%7D%7B14%7D%29%5E2%3D%5Cfrac%7B550%7D%7B343%7D%20cm%5E2)
No. of circles can be cut = ![\frac{\frac{500}{49}}{\frac{550}{343}}=6.3636](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B500%7D%7B49%7D%7D%7B%5Cfrac%7B550%7D%7B343%7D%7D%3D6.3636)
So,Nancy can cut 6 full circles
