Question 1126410

simon saw antelopes and crows in the meadow at the zoo. He counted 26 heads and 66 legs. How many antelopes did he see?
<pre>Let number of antelopes and crows be A, and C, respectively
Then we get: A + C = 26 ------- eq (i)
Also, 4A + 2C = 66______2(2A + C) = 2(33)______2A + C = 33 ------ eq (ii)
Subtracting eq (i) from eq (ii), we get: A, or number of antelopes = {{{highlight_green(matrix(1,3, 33 - 26, "=", 7))}}}
