Is the equation a correct first step to solving 3(6 + x) = 24?

[Deleted User]

Drag each equation to show if it could be a correct first step to solving the equation 3(6 + x) = 24.

18 + x = 24
(3 • 6) + (3 • x) = 24
6 + x = 8
3(6 + x) = 72
6 + 3x = 24
18 + 3x = 24

Yes
No

  1. To determine if each equation could be a correct first step in solving the equation (3(6 + x) = 24), we can analyze them one by one.

    1. 18 + x = 24No (This implies removing multiplication incorrectly.)
    2. (3 • 6) + (3 • x) = 24Yes (This is distributing correctly.)
    3. 6 + x = 8No (This is an incorrect simplification.)
    4. 3(6 + x) = 72No (This changes the original equation incorrectly.)
    5. 6 + 3x = 24No (This incorrectly rearranges the equation.)
    6. 18 + 3x = 24Yes (This results from the correct distribution leading to further steps.)

    In summary:

    Yes: (3 • 6) + (3 • x) = 24, 18 + 3x = 24

    No: all others
