Compare Expressions: Is 18x Equal to 2+9x?

To determine if the expressions $18x$ and $2 + 9x$ are equivalent, we'll analyze their structures.

• $18x$ is a linear expression with a single term involving the variable $x$, and its coefficient is 18.
• $2 + 9x$ consists of two terms: a constant term $2$ and a linear term $9x$ with coefficient 9.

For two expressions to be equivalent, each corresponding term must be equal. Here, the expression $18x$ has no constant term, whereas $2 + 9x$ has a constant term of 2. Furthermore, the linear term coefficients differ: $18 \neq 9$.

Therefore, the expressions $18x$ and $2 + 9x$ are not the same. They structurally differ and cannot be made equivalent just through similar values of $x$.

Therefore, the solution to this problem is: No.
