Question

7 simplify the expression: 8 - 4y + (-2y) + 5

Explanation:

Step1: Combine constant terms

First, identify the constant terms (terms without \( y \)): \( 8 \) and \( 5 \). Add them together: \( 8 + 5 = 13 \).

Step2: Combine like variable terms

Next, identify the terms with \( y \): \( -4y \) and \( -2y \). Add their coefficients: \( -4y + (-2y) = -6y \).

Step3: Combine the results

Now, combine the combined constant term and the combined variable term: \( 13 - 6y \).

Answer:

\( 13 - 6y \)
