Question

13 minus quarter of a number is equal to 15 less than the same number”​

Answer 1

х - is a number.

x/4 - is quarter of a number.

x - (13 - x/4) = 15

x - 13 + x/4 = 15

x + x/4 = 15 + 13

4x/4 + x/4 = 28

5x/4 = 28

x = 28•4/5

x = 22,4

Verification

13 - 22,4/4 + 15 = 13 - 5,6 + 15 = 22,4

Answer 2

Let's call the number you're trying to find "x."

According to the information you provided, the equation can be written as:

13 - (1/4)x = x - 15

Now, let's solve for x:

First, get rid of the fractions by multiplying both sides of the equation by 4 to clear the fraction:

4(13 - (1/4)x) = 4(x - 15)

Now, distribute the 4 on both sides of the equation:

52 - x = 4x - 60

Next, let's isolate x on one side of the equation. Add x to both sides of the equation:

52 - x + x = 4x - 60 + x

52 = 5x - 60

Now, add 60 to both sides:

52 + 60 = 5x - 60 + 60

112 = 5x

Finally, divide both sides by 5 to solve for x:

(112)/5 = (5x)/5

x = 22.4

So, the number you're looking for is 22.4.
