Answer:
![\large\boxed{3\sqrt7}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B3%5Csqrt7%7D)
Step-by-step explanation:
![\text{Geometric mean:}\\\\\underbrace{\sqrt[n]{a_1\cdot a_2\cdot a_3\cdot...\cdot a_n}}_n\\\\\sqrt{7\cdot9}=\sqrt{9}\cdot\sqty7=3\sqrt7](https://tex.z-dn.net/?f=%5Ctext%7BGeometric%20mean%3A%7D%5C%5C%5C%5C%5Cunderbrace%7B%5Csqrt%5Bn%5D%7Ba_1%5Ccdot%20a_2%5Ccdot%20a_3%5Ccdot...%5Ccdot%20a_n%7D%7D_n%5C%5C%5C%5C%5Csqrt%7B7%5Ccdot9%7D%3D%5Csqrt%7B9%7D%5Ccdot%5Csqty7%3D3%5Csqrt7)
The answer should be -192. I could explain in the comments if you would like. :)

Answer:
268.08
Step-by-step explanation:
Solving for the value that makes both true
dvide the left equation by 3 to simplify
3x-2y=1
oh, they are same equaiton
inifnite solutions
the solutions are the points on the line y=(3/2)x-(1/2)
