Question

The sum of two number is 15 and thir is 1 difference

Answer 1

Number first = 8

Number second = 7

Step-by-step explanation:

Given:

Sum of two number = 15

Difference of two number = 1

Assume;

Number first = x

Number second = y

Computation:

x + y = 15.....eq1

x - y = 1......eq2

eq1 - eq2

So,

2x = 16

x = 8

Number first = 8

x + y = 15

8 + y = 15

y = 7

Number second = 7
