Answer:
x=-1
Step-by-step explanation:
<em>Add by 1 from both sides of equation.</em>
<em>9x-1+1=-11+1</em>
<em>Simplify.</em>
<em>-11+1=-10</em>
<em>9x=-10</em>
<em>Divide by 9 from both sides of equation.</em>
<em>9x/9=-10/9</em>
<em>Simplify, to find the answer.</em>
<em>x=-10/9</em>
<em>x=-1 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>

Answer:
The highway fence cost $600.
Step-by-step explanation:
Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.
Therefore, we use
$1800 / highway fence(2 normal fence) + 4 normal fence
$1800 / (2 + 4) = $300
This means that every normal fence cost $300.
Which then we get the highway fence is $600 because it costs double of the normal fence.
