what is a number that when you subtract 12 then divide the difference by 3, to get 6
algebraic solution:
(x - 12)/3 = 6
multiply both sides by 3
x - 12 = 18
x = 18+12 = 30
Let's call the unknown number "x". According to the given information, the steps are as follows:
1. Subtract 12 from the unknown number: x - 12
2. Divide the result by 3 to get 6: (x - 12) ÷ 3 = 6
To find the value of "x", we can solve the equation.
(x - 12) ÷ 3 = 6
1. Multiply both sides of the equation by 3 to eliminate the division: (x - 12) = 6 * 3
2. Simplify the right side: (x - 12) = 18
3. Add 12 to both sides to isolate "x": x = 18 + 12
Therefore, the unknown number "x" is 30.
Let's solve the problem step by step.
First, let's assume the number as "x". According to the problem, when we subtract 12 from this number, we get the difference.
So, the first step is to subtract 12 from x: x - 12.
Next, we are instructed to divide the difference obtained by 3 and the result should be 6.
So, the equation becomes: (x - 12) / 3 = 6.
To find the value of x, we need to isolate it.
Multiply both sides of the equation by 3 to cancel out the division:
(x - 12) = 6 * 3.
Simplify the right side:
(x - 12) = 18.
Finally, to get x, we will add 12 to both sides of the equation:
x = 18 + 12.
x = 30.
Therefore, the number we are looking for is 30.
