Question

Medal! Fan!!! Help please!
This section focuses on identities. What is the difference between an identity and an equation? Expound and prove your point with examples.

Answer 1

an identity is an equation that is true no matter what \(x\) is
for example :\[x=x\\
2x=x+x\\
2(x+1)=2x+2\] those are all identities, you can plug in any number in the left and right and the equal sign will be true

Answer 2

an equation that is not an identity is one that is true for some value or values of \(x\) but not all
for example
\[x=3\\
2x=6\\
2x+5=11\] are true only if \(x=3\) not for any number

Answer 3

Thank you! I understand now
