Dr. Johnson’s Calculation Error
Initial Calculation Plan
Dr. Johnson was engaged in calculations for his work, where he intended to multiply a specific number by 0.5 and then add 3 to the outcome.
Distraction and Error
However, he became distracted and mistakenly divided the same number by 0.5 and subtracted 3 from the result. Surprisingly, despite the error, he arrived at the correct answer.
Finding the Number
The number Dr. Johnson used in his calculations can be determined. Let X represent this number. Since he achieved the correct result, the following equation holds true: 0.5X + 3 = 2X – 3.
Solving for X
By solving the equation, we find that X equals 4.
