Question

find the sum.
the sum $(5z + 4) + (3z - 6)$ is $\square$.

Explanation:

Step1: Remove parentheses

To add the two expressions \((5z + 4)+(3z - 6)\), we first remove the parentheses. This gives us \(5z + 4+3z - 6\).

Step2: Combine like terms

Next, we combine the like terms. For the \(z\)-terms: \(5z+3z = 8z\). For the constant terms: \(4 - 6=-2\).

Step3: Write the result

Combining these results, we get \(8z-2\).

Answer:

\(8z - 2\)
