Final answer:

To find the number, set up an equation using the given information and solve for the variable 'x'. The number is x = 43.

Step-by-step explanation:

To find the number, we need to set up an equation using the given information. Let's use the variable 'x' to represent the unknown number. The sum of 38 and twice a number is 124, so we can write the equation as: 38 + 2x = 124. To solve this equation, we need to isolate the variable 'x'. First, subtract 38 from both sides of the equation: 2x = 124 - 38. Simplifying, we have 2x = 86. Finally, divide both sides of the equation by 2: x = 86 ÷ 2. Therefore, the number is x = 43.

38 + 2n = 124

2n = 124 - 38

2n = 124 - 24 - 14

2n = 86

Therefore:

n = 43
