I add 18 to 3times a number the result is equal to 5times the number.what is the number
Let's represent the number as "x".
The equation can be written as:
18 + 3x = 5x
Simplifying the equation:
18 = 2x
Dividing both sides by 2:
x = 9
Therefore, the number is 9.
To find the number, let's assign a variable to it. Let's say the number is "x".
According to the given information, we can write the equation:
18 + 3x = 5x
Now let's solve this equation step by step:
1. Subtract 3x from both sides of the equation:
18 = 5x - 3x
2. Simplify the equation:
18 = 2x
3. Divide both sides of the equation by 2:
x = 18 / 2
4. Evaluate the division:
x = 9
Therefore, the number is 9.
To solve this problem, let's represent the unknown number using a variable. Let's call the number "x."
According to the problem, "I add 18 to 3 times a number." This can be written as 3x + 18.
The problem also states, "The result is equal to 5 times the number." This can be written as 5x.
Now, we can set up an equation:
3x + 18 = 5x
To solve for x, we want to isolate it on one side of the equation. We can do this by subtracting 3x from both sides:
18 = 5x - 3x
Simplifying the equation, we get:
18 = 2x
To solve for x, we divide both sides of the equation by 2:
18/2 = x
Simplifying further, we get:
9 = x
Therefore, the number is 9.
