Question

if the number exceed by 12 if their sum is 72 find the number​

Answer 1

Answer:

numbers are 42 and 30

Step-by-step explanation:

let the unknown number be X and y

a/q

x= y +12.......i)

and

x+y=72

which means

x=72 -y........ii)

on substituting value of x in equation 1 ,we get

72 - y = y + 12

72-12=2y

y = 60/2

y=30

by placing value of y in equation ii), we get

x = 72 -30

X= 42

hence the 2 numbers are 30 and 42
