are the following equations an identity?

Question

7m - 2 = 8m +4 - m

Answer 1

To determine if the equation is an identity, we need to simplify both sides of the equation and check if they are equal.

Starting with the left side:
7m - 2

Now, let's simplify the right side:
8m + 4 - m
= 7m + 4

Now we compare both sides of the equation:
7m - 2 = 7m + 4

These two sides are not equal, so the given equation is not an identity.
