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>
