Verified step by step guidance
1
Identify the expression to simplify: \$10 - (4y + 8)$.
Apply the distributive property to remove the parentheses by multiplying the minus sign with each term inside: \$10 - 4y - 8$.
Combine like terms (constants) by subtracting 8 from 10: \((10 - 8) - 4y\).
Simplify the constants to get \$2 - 4y$.
Write the final simplified expression as \$2 - 4y$.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Distributive Property

The distributive property allows you to multiply a single term across terms inside parentheses. For example, a(b + c) = ab + ac. In subtraction, it helps to remove parentheses by distributing the negative sign across the terms inside.
