<span>An equation that is satisfied for every value of the variable for which both sides are defined is called an identity.
For example:
Given the equation
3x + 4 = x + 2(x + 2)
Notice that for any value of x you use, the equation is true.
Thus, this type of equation is called an identity.

Answer:
th answer i think is thirty
Step-by-step explanation:
30 + 10 = 40 and it said at most $50
tell me if i'm wrong
<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
42 can be
1 x 42, or
2 x 21, or
3 x 14, or
6 x 7 .
