Question

sum of two number is 72. if the number exceeds the other by 12 .find the number?

Answer 1

Since you insisted to solve in on variable, here we go

The numbers are x and x+12

x+x+12 = 72
2x = 60
x = 30

x+12 = 42

So, the numbers are 30 and 42

Answer 2

x+x+12 = 72
2x+12=72
2x = 72-12
2x = 60
x = 60/2
x = 30
x+12 = 30+12 = 42
no. are 30 and 42
