What is the first step in determining if 6 is a solution to [tex]3x = 18[/tex]?

A. Substitute 6 for [tex]x[/tex] in the equation.
B. Rewrite [tex]3x[/tex] as 36.
C. Multiply 3 and 18.
D. Divide 6 by 3.

Answer :

To determine if 6 is a solution to the equation [tex]\(3x = 18\)[/tex], follow these steps:

1. Substitute 6 for [tex]\(x\)[/tex] in the equation: Replace [tex]\(x\)[/tex] in the equation with the number 6. So, the equation becomes [tex]\(3 \times 6\)[/tex].

2. Calculate the expression: Multiply 3 by 6. This gives us [tex]\(18\)[/tex].

3. Check if this is equal to 18: After calculating, compare the result to 18. If it equals 18, then 6 is indeed a solution to the equation.

Since [tex]\(3 \times 6 = 18\)[/tex], the equation holds true. Therefore, the first step in verifying if 6 is a solution is to substitute 6 for [tex]\(x\)[/tex] in the equation and check the result.
