It looks like your expression is incomplete. Do you mean to calculate $5 + 7 \times x$, where $x$ is a variable?

If so, the result depends on the value of $x$. To solve it, you would use the standard order of operations (PEMDAS/BODMAS), meaning you would multiply first, then add.

So: $5 + 7x = 5 + (7 \times x)$

If you provide a value for $x$, I can help you calculate the result. Let me know!

Do you have any questions or need further details?

Here are 5 related questions:

1. What is the value of $x$ in this expression?
2. Would you like help simplifying other algebraic expressions?
3. Are you familiar with the order of operations in math?
4. How would this expression change if you added parentheses?
5. Do you want to learn about how to solve for $x$ in equations?

Tip: When simplifying expressions, always follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
