One half of a number minus 9 is 14
12
To solve this problem, let's break it down step-by-step:
Step 1: Let's assume the number is represented by the variable "x".
So, "One half of a number" can be written as (1/2)x.
Step 2: "One half of a number minus 9" can be written as (1/2)x - 9.
Step 3: According to the problem, (1/2)x - 9 equals 14.
So, we can write the equation as (1/2)x - 9 = 14.
Step 4: Now, let's solve the equation to find the value of x.
Add 9 to both sides of the equation to isolate (1/2)x:
(1/2)x - 9 + 9 = 14 + 9
Simplifying this equation, we get:
(1/2)x = 23.
Step 5: To get rid of the fraction, we can multiply both sides of the equation by 2:
2 * (1/2)x = 2 * 23
Simplifying this equation, we get:
x = 46.
Therefore, the number is 46.
To solve this equation, we'll work step by step:
Let's start by assuming the number is "x".
"One half of a number" can be expressed as "x/2".
"Minus 9" can be written as "-9".
Putting it all together, we have the equation:
x/2 - 9 = 14
To isolate x, we need to get rid of the -9 on the left side of the equation. To do this, we'll add 9 to both sides:
x/2 - 9 + 9 = 14 + 9
Simplifying, we have:
x/2 = 23
Next, we need to get rid of the division by 2. Multiplying both sides by 2 will accomplish this:
2 * (x/2) = 2 * 23
Simplifying, we have:
x = 46
Therefore, the number is 46.
solve for x
(1/2)x - 9 = 14
you should be able to solve this equation in your head.
