Combine the like terms to create an equivalent expression:
{-3z-z}−3z−z
{-3z-z}−3z−z = -4z -3z - z = -8z.
To combine like terms, we need to add or subtract the coefficients of the similar terms. In this case, the similar terms are -3z and -z.
{-3z - z} - 3z - z
Combining the coefficients of -3z and -z, we get -3 - 1, which is -4.
So the equivalent expression is:
-4z - 3z - z
Simplifying further:
-7z - z
The final equivalent expression is:
-8z
To combine like terms, we need to add or subtract the coefficients of the same variable. In this case, we have two variables, z and -z.
First, let's combine the z terms. We have -3z - z. To add these, we add their coefficients:
-3z - z = -3z - 1z = -4z.
Now, let's combine the -z terms. We have -3z - z and -3z - z. Again, we add their coefficients:
-3z - z = -3z - 1z = -4z.
Finally, the expression becomes:
-4z - 3z - z.
Combining like terms, we get:
-4z - 3z - z = -8z.
