Answer:
q = r
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given 2q – r = 4p ...(i)
2r = q...(ii)
r = 2p ...(iii)
Substitute 2r = q in equation (i)
<em> 2(2r) – r = 4p </em>
3 r = 4 p
<em> 2 r + r = 4 p</em>
2 r + 2 p = 4 p
2 r = 2 p
<em> q = r</em>
This you answer x=-1/5y+-4/5

Answer:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴ 
∴
- equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴ 
Now, lets put the value of y from equation 1
⇒ 
⇒ 
⇒ 
∴ 
Next, substituting the value of x in equation 1

⇒ 
∴ 
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.
