Problem:
Write the given information in equation form: One-third of x is four more than the sum of what number must be added to 30 to get 2q.

Solution:
To express the given information in equation form, we can break it down into steps:

Step 1: Define the unknown quantities:
Let x be the unknown number we are trying to find.
Let q be another unknown number.

Step 2: Translate the given information into equations:
One-third of x is four more than the sum of what number must be added to 30 to get 2q.
To express this in equation form, we can use the following steps:

Step 3: Express "One-third of x":
One-third of x can be written as x/3.

Step 4: Express "the sum of what number must be added to 30":
Let y be the unknown number that needs to be added to 30.
The sum of y and 30 can be written as y + 30.

Step 5: Express "four more than the sum of what number must be added to 30":
Four more than the sum of y and 30 can be written as y + 30 + 4.

Step 6: Express "2q":
2q can be written as 2q.

Step 7: Combine all the expressions to form the equation:
From step 3 and step 5, we have: x/3 = y + 30 + 4

From step 6, we have: 2q

Step 8: Final equation:
Combining step 7 and step 6, we have: x/3 = y + 30 + 4 = 2q

Thus, the equation form of the given information is x/3 = y + 30 + 4 = 2q.
