<em>These can be set up as systems of equations.</em>
<em> </em>
<em>Let b = the number of birds, and let d = the number of dogs.</em>
<em> </em>
<em>b + d = 21</em>
<em> </em>
<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>
<em> </em>
<em>You can solve this using either elimination or substitution.</em>

<em>Consider marking brainliest.</em>
