<span>у теленка -----4 ноги</span>
<span><span>у цыпленка---- 2 ноги</span></span>
<span><span><span> всего ----------46 ног</span></span></span>
<span><span><span>
</span></span></span>
<span><span>если ---------<span> х телят</span></span></span>
<span><span><span> тогда -------16-х цыплят</span></span></span>
<span><span><span>
</span></span></span>
<span><span><span>составим уравнение</span></span></span>
<span><span><span><span>4х + 2*(16-х) = 46</span></span></span></span>
<span><span><span><span>4х+32-2х=46</span></span></span></span>
<span><span><span><span>4х-2х=46-32</span></span></span></span>
<span><span><span><span>2х=14</span></span></span></span>
<span><span><span><span>х=14:2</span></span></span></span>
<span><span><span><span>х=7 ---телят</span></span></span></span>
<span><span><span><span>
</span></span></span></span>
<span><span><span><span>16-7=9 цыплят.</span></span></span></span>
