Thomas is thinking of a number, if he doubles his number and subtracts 27, he gets 407. Whats his number?
2x - 27 = 407
Paul was thinking of a number. Paul doubles it and gets an answer of 13.1. What was the original number
Let's denote the number that Thomas is thinking of as "x".
According to the problem, when Thomas doubles his number and subtracts 27 from it, he gets 407. Therefore, we can write the equation as:
2x - 27 = 407
To find the value of x, we will isolate the variable x by adding 27 to both sides of the equation:
2x - 27 + 27 = 407 + 27
2x = 434
Next, we divide both sides of the equation by 2 to solve for x:
2x/2 = 434/2
x = 217
Therefore, Thomas's number is 217.
To find Thomas's number, we can solve the equation: 2x - 27 = 407, where x represents his number.
To solve this equation, we need to isolate x by performing the following steps:
1. Add 27 to both sides of the equation to eliminate the -27 on the left side:
2x - 27 + 27 = 407 + 27
Simplifying gives: 2x = 434
2. Divide both sides of the equation by 2 to isolate x:
(2x)/2 = 434/2
Simplifying gives: x = 217
Therefore, Thomas's number is 217.
