Five time a number is subtracted 13. If the difference is 28, find the number
Good
How to solve
Sincerely pius
Sorry. I do not understand what you mean.
Assuming you meant to say:
"Five time a number is subtracted from 13."
13 - 5x = 28
-5x = 15
x = -3
check:
5 times our number is -15
this is subtracted from 13
13 - (-15) = 13 + 15 =28
All looks good
To find the number, we can set up an equation based on the given information. Let's call the unknown number "x". According to the problem, "Five times a number is subtracted 13" can be written as 5x - 13. We are told that the difference is 28, so we can set up the equation:
5x - 13 = 28
To solve for x, we need to isolate it on one side of the equation. Let's start by adding 13 to both sides:
5x - 13 + 13 = 28 + 13
5x = 41
Next, we divide both sides of the equation by 5 to solve for x:
(5x)/5 = 41/5
x = 41/5
x = 8.2
So the number is 8.2.
