Question

simplify the expression: -1 + -8z + -6z + -7z - 6 + 5z

Explanation:

Step1: Combine constant terms

The constant terms are -1 and -6. We add them together: $-1 + (-6) = -7$

Step2: Combine like terms (z terms)

The z terms are -8z, -6z, -7z, and 5z. We add their coefficients: $-8 + (-6) + (-7) + 5 = -8 - 6 - 7 + 5 = -16$

Step3: Combine the results from Step1 and Step2

We combine the constant term and the z term: $-16z - 7$

Answer:

$-16z - 7$
