Half the sum of a number and 26 is 15

Answer 1

Let's call the number "x". The sum of a number and 26 is written as x + 26.

According to the problem, half the sum of a number and 26 is 15. So, we can write this as:

(x + 26) / 2 = 15

To solve for x, we can eliminate the fraction by multiplying both sides of the equation by 2:

2 * (x + 26) / 2 = 15 * 2

This simplifies to:

x + 26 = 30

Now, we can isolate x by subtracting 26 from both sides:

x = 30 - 26

This simplifies to:

x = 4

Therefore, the number is 4.
