Answer 2

To solve this algebraic expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you should first perform the operations inside the parentheses, then do the multiplication and subtraction:

1. Inside the parentheses, you have 3 + 4, which equals 7.
2. Now, the expression becomes 5 * 7 - 7.
3. Next, multiply 5 by 7, which equals 35.
4. Finally, subtract 7 from 35 to get the final result: 35 - 7 = 28.

So, the value of the expression 5x(3+4)-7 is 28.
