The sum of 3 times some number and 18 is 33. What is the number?
3n + 18 = 33
3n = 15
n = ?
Suppose that the required number=x A/q 3x+18=33 or,3x=33-18 or,3x=15 or,x=15/3=5 so, required number=5
To find the number, we can set up an equation based on the problem statement. Let's call the number we're trying to find "x."
The sum of 3 times the number and 18 is 33 can be written as:
3x + 18 = 33
To solve for x, we need to isolate it on one side of the equation. Start by subtracting 18 from both sides:
3x + 18 - 18 = 33 - 18
Simplifying, we get:
3x = 15
Next, we want to get x by itself, so we divide both sides of the equation by 3:
3x/3 = 15/3
The 3's cancel out on the left side, leaving us with:
x = 5
Therefore, the number we're looking for is 5.
