Hi.
This question is about math.
<em>Subtract by the 7 from both sides.</em>
<em>Simplify</em>
Explanation: First you had to subtract by the 7 from both sides. Then simplify, the answer should be x>-12. In that's its how it work. Hope this helps you. Thank you for posting your question at here on Brainly. -Charlie
Answer: There are 8 snake and 3 elephants.
Step-by-step explanation:
Let x= Number of snakes
y= Number of elephants
We know that , snake has no legs elephant has 4 legs.
Then, Total animals = x+y=11 (i)
Total legs = 4y = 12
⇒ y=3 .. (ii)[divide both sides by 4]
Substitute value of y from (ii) in (i) , we get
Hence, there are 8 snake and 3 elephants.
