Answer :
To determine whether $6$ is a solution to the equation
$$3x = 18,$$
the very first step is to substitute $6$ for $x$.
Here is a step-by-step explanation:
1. **Substitute $6$ for $x$:**
Replace $x$ with $6$ in the equation. This gives:
$$3(6) = 18.$$
2. **Compute the left-hand side:**
Calculate $3 \times 6$:
$$18 = 18.$$
3. **Verify the equality:**
Since both sides of the equation are equal (i.e., $18 = 18$), $6$ is indeed a solution.
Thus, the first step is to substitute $6$ for $x$ in the equation.
