I think of a number double it and add 14. The result is 36. What is the number? With working
2x+14=36
2x=36-14
2x/2=22/2
X=11
I thought of a number, and when I doubled it the result was four less than a score. What was the number?
I thought of a number doubled it then added 3 .the result multiplied by 4came to 52 what was the number I thought of?

Solve for x.
The classroom clock which is five minutes fast shows that it is 3: 08pm. What is the correct time?
Student
To find the number, let's break down the problem step by step.
Let's assume the unknown number is represented by "x."
Step 1: "Double the number." This can be represented as 2x.
Step 2: "Add 14 to the doubled number." This can be expressed as 2x + 14.
According to the problem, the result of this expression is 36. Therefore, we can set up an equation:
2x + 14 = 36
Now, let's solve for x:
Subtract 14 from both sides of the equation:
2x + 14 - 14 = 36 - 14
2x = 22
Divide both sides of the equation by 2 to isolate the variable x:
(2x)/2 = 22/2
x = 11
Therefore, the unknown number is 11.
