Final answer:
To determine the number, write and solve the equation 1 + 3x = 22. The number is 7.
Step-by-step explanation:
To write and solve an equation to determine the number in this problem, we can use the given information. The problem states that the sum of 1 and 3 times a number is 22. Let's start by assigning a variable to represent the unknown number. Let's call it x. The equation representing this problem would be 1 + 3x = 22. To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 1 from both sides of the equation, giving us 3x = 21. Finally, we can solve for x by dividing both sides of the equation by 3, which gives us x = 7. Therefore, the number is 7.
