Answer:
90 and 8
Step-by-step explanation:
The question is : the sum of two numbers is 98 and their difference is 82 find the two numbers
Let two numbers are x and y.
Sum of two numbers is 98
x+y = 98 ....(1)
The difference of two numbers is 82.
x-y=82....(2)
Adding equation (1) and (2) we get :
x+y+x-y=98+82
2x=180
x=90
Put the value of x in equation (1)
90+y = 98
y = 8
Hence, the two numbers are 90 and 8.
