A number subtracted from 13 is the quotient of -34and 2. Find the number
-34/2 = 13 - n
-34 = 26 - 2n
-34 + -26 = 2n
-60 = 2n
-30 = n
When twice a certain number is subtracted from 13 find the number
To find the number, let's follow these steps:
Step 1: Write down the given information.
A number subtracted from 13: 13 - x
The quotient of -34 and 2: -34 / 2
Step 2: Set up an equation using the given information.
We are told that the number subtracted from 13 is equal to the quotient of -34 and 2. So we can write the equation as:
13 - x = -34 / 2
Step 3: Simplify the equation.
-34 divided by 2 is -17, so the equation becomes:
13 - x = -17
Step 4: Solve the equation for x.
To isolate x, we need to get rid of 13 on the left side of the equation. We can do this by subtracting 13 from both sides:
13 - 13 - x = -17 - 13
This simplifies to:
-x = -30
Next, we want to solve for x by isolating it on one side of the equation. To do this, we multiply both sides of the equation by -1:
(-1)(-x) = (-1)(-30)
This gives us:
x = 30
So, the number that, when subtracted from 13, gives the quotient of -34 and 2 is 30.
