are the following equations an identity?
7m - 2 = 8m +4 - m
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.
To determine if the given equations are an identity, we need to simplify them and check if they are true for all values of m.
Starting with the left side of the equation:
7m - 2
And simplifying the right side of the equation:
8m + 4 - m
Combining like terms on the right side:
7m + 4
Now we have:
7m - 2 = 7m + 4
If we subtract 7m from both sides, we get:
-2 = 4
This is not a true statement. Therefore, the given equations are not an identity.
To determine if the given equation is an identity, we need to simplify both sides of the equation and check if they are equal.
Let's simplify the equation step by step:
Starting with the left-hand side (LHS):
7m - 2
Now, let's simplify the right-hand side (RHS):
8m + 4 - m
Combining like terms, we have:
(8m - m) + 4
Simplifying further:
7m + 4
Now, let's compare the simplified LHS and RHS:
LHS: 7m - 2
RHS: 7m + 4
Since the simplified LHS (7m - 2) is not equal to the simplified RHS (7m + 4), the given equation is not an identity.
Therefore, the equation 7m - 2 = 8m + 4 - m is not an identity.
