Answer:

<em>B=-3</em>

Step-by-step explanation:

<em>-11b+7=40</em>

<em />

<em>Subtract -7 from both sides</em>

<em />

<em>-11b-7=40-7</em>

<em />

<em>11b=33</em>

<em />

<em>divide by -11</em>

<em />

<em>11b/-11=33/-11</em>

<em />

<em>-11 and -11 cancel out, leaving you with B=-33/11</em>

<em />

thus B=-3
