Problem 92
Question
Simplify each algebraic expression. $$4(5 y-3)-(6 y+3)$$
Step-by-Step Solution
Verified Answer
The simplified expression is \(14y - 15\).
1Step 1: Apply the Distributive Property
Firstly, apply the distributive property on the first term, which results in \(4 \times 5y\) and \(4 \times -3\). This results in \(20y - 12\). Therefore, the expression becomes \(20y - 12 -(6y + 3)\).
2Step 2: Distribute the Negative Sign
Next, distribute the negative sign across the \(6y\) and \(3\) in the second set of parentheses. This changes the sign of each term within the parentheses, resulting in \(-6y - 3\). The expression now becomes \(20y - 12 - 6y - 3\).
3Step 3: Combine Like Terms
Finally, combine the terms \(20y\) and \(-6y\) to get \(14y\), and combine the terms \(-12\) and \(-3\) to get \(-15\). Thus, the fully simplified expression is \(14y - 15\).
