the sum of a certain number and 8 is 23 what is the number?
I do not get this cause I also have to write the equation

Respuesta :

Answer: 15

Step-by-step explanation:

The sum means that the equation will be an addition problem.

The question tells us that 8 and another number is equal to 23.

The unknown number we will say is x.

x + 8 = 23

Now we solve the equation for x by subtracting the 8 from both sides.

x = 15

15+8=23 the number is 15
