Answer
7
Answer for screen readers
The evaluated expression $3x + 1$ for $x = 2$ is 7.
Steps to Solve
-
Identifying the expression to evaluate or solve First, determine if you need to evaluate the expression for a specific value of $x$ or solve for $x$. Let's assume you want to evaluate it for a specific value, for example, $x = 2$.
-
Substituting the value of x Substitute $x$ with the chosen value in the expression $3x + 1$. For $x = 2$, the expression becomes: $$ 3(2) + 1 $$
-
Performing the multiplication Multiply the coefficient 3 by the value of $x$: $$ 3 \times 2 = 6 $$
-
Adding the constant term Now, add the constant term from the expression to the result of the multiplication: $$ 6 + 1 = 7 $$
So, when $x = 2$, the expression $3x + 1$ evaluates to 7.
The evaluated expression $3x + 1$ for $x = 2$ is 7.
More Information
To evaluate this expression, you simply substitute the value of $x$ and perform basic arithmetic operations. It's a straightforward procedure often used in algebra.
Tips
- Failing to correctly substitute the value of $x$ into the expression.
- Forgetting to perform multiplication before addition, which is a common arithmetic mistake. Always follow the order of operations (PEMDAS/BODMAS).
