The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14. Find the number

Required numbers are x = -0.5 and y =18.6

Step-by-step explanation:

Let the two numbers be x and y

Their sum is 18 i.e x+y= 18

4/7y-5x= 14

We need to find the numbers x and y

Solving both equations to find value of x and y

From equation 1 we can find value of x and put in equation 2 i.e

x=18-y

Putting the value of x in equation 2

Now finding x

So, Required numbers are x = -0.5 and y =18.6

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
