Answer: The width of the rectangular space = 3/2 miles
Answer:
![x=1](https://tex.z-dn.net/?f=x%3D1)
Step-by-step explanation:
So we have the equation:
![30-3x=15+12x](https://tex.z-dn.net/?f=30-3x%3D15%2B12x)
First, let's add 3x to both sides. The left side cancels:
![30=15+15x](https://tex.z-dn.net/?f=30%3D15%2B15x)
Now, subtract 15 from both sides. The right cancels:
![15=15x](https://tex.z-dn.net/?f=15%3D15x)
Divide both sides by 15:
![x=1](https://tex.z-dn.net/?f=x%3D1)
So, the value of x is 1.
And we're done!
