Simplify the expression: 5(2x - 3) + 4x.

Simplify the expression: 5(2x - 3) + 4x.

• A. 14x - 15
• B. 10x - 15
• C. 14x + 15
• D. 8x - 15

Answer: (A)

Distribute and combine like terms. Multiply 5 by each part inside the parentheses: 5(2x) gives 10x, and 5(-3) gives -15. So you have 10x - 15, and then add the remaining 4x: 10x - 15 + 4x. Combine the x terms to get 14x, while the constant stays -15. The simplified expression is 14x - 15. The negative sign on the constant is important, and the x-terms must be added together since they share the same variable.
