Question

All identities are equations, and all equations are identities. True or false?

Answer 1

\[x+2=7\]

Answer 2

I think true, since both share the "equality" condition?

Answer 3

An identity is true for all values of x. An equation is true for only certain values of x.

Answer 4

\[x^2=x\times x\]
This is an identity
Equations are true for only a set of values
\[x^2+2x+1=0\]
True for only x=-1

Answer 5

So it is false?

Answer 6

yup

Answer 7

not all equations are identities
