Chisom thinks of a number, she add three to it and then divide the result by five .if the answer equals the original number.what is the number please i need the solution
c+3/5=c
Cross multiply to get
C+3=5xc
C+3=5c
Collect like terms to get
C-5c=-3
-4c=-3
Divide both side by-4 to get ur answer
I need the solution
(n+3)/5 = n
n + 3 = 5 n
4 n = 3
n = 3/4
Well, if Chisom adds three to a number and then divides the result by five, and the answer is equal to the original number, it means that the original number must be 0. Why? Because if you add three to 0, you get 3, and dividing 3 by 5 gives you a fraction less than 1. So, in this case, the number Chisom was thinking of is 0.
To find the number, let's set up an equation based on the given information. Let's call the number Chisom thinks of "x".
According to the problem, Chisom adds three to the number and then divides the result by five. So, the equation can be written as:
(x + 3) / 5 = x
To solve this equation, we can start by multiplying both sides of the equation by 5 to get rid of the fraction:
5 * (x + 3) / 5 = 5 * x
This simplifies to:
x + 3 = 5x
Next, we can subtract x from both sides of the equation to isolate the x term:
3 = 5x - x
Simplifying this further, we get:
3 = 4x
Lastly, we divide both sides of the equation by 4 to solve for x:
3/4 = x
Therefore, the number Chisom is thinking of is 3/4, which is equivalent to 0.75.
