Question: evaluating algebric
1. The problem is to evaluate an algebraic expression or solve an algebraic problem.
2. Algebra involves using variables, constants, and operations like addition, subtraction, multiplication, and division.
3. To evaluate an algebraic expression, substitute the given values for variables and simplify step-by-step.
4. For example, if the expression is $2x + 3$ and $x=4$, substitute to get $2(4) + 3$.
5. Simplify multiplication first: $2 \times 4 = 8$.
6. Then add: $8 + 3 = 11$.
7. The final answer is $11$.
This is a general approach to evaluating algebraic expressions.
