Half the sum of a number and 26 is 15. What is the number?(1 point)

1 answer

Let's represent the number with the variable x.

The given information can be written as an equation: (1/2)x + 26 = 15

To solve for x, we need to isolate it on one side of the equation.

Subtract 26 from both sides: (1/2)x = 15 - 26

Simplify: (1/2)x = -11

To solve for x, we multiply both sides by 2: x = -11 * 2

Simplify: x = -22

The number is -22.
